Gen 1

The GEN 1 series is INIVEN’S first generation of telemetry equipment, often used in applications where turning on/off a device remotely is needed. The GEN 1 series sends digital and analog data over voice grade phone circuits (300-3500Hz), and are usable in a number of racks, including 3U 19”, 1U 19” and wall mount versions with or without built in power supplies. It is also available with either passive elements or the full programmability of digital signal processing (DSP) technology. In many cases, INIVEN’S GEN 1 equipment can operate in competitor’s enclosures and is pin for pin compatible with most Quindar, Sparling, QEI and DAQ equipment.

Gen 1 Series 30 & Gen 1 Series 10

There are two sub-series in the GEN 1 line, the 30 and the 10 Series. The 30 Series consists of a wide range of products that communicate using frequency shift keying (FSK). Transmitters and receivers are available to communicate single status points, single analog points and multiplexed status and analog points in a single unit.

The 10 Series uses amplitude modulation (AM) making it ideal for the replacement of existing equipment whereas the technology of the 30 series makes it more appropriate for new projects.

A large list of power supplies and accessories including replacement parts for other manufacturer’s equipment are available.

As with all Iniven equipment, Gen 1 is supported by a 12 year warranty.

IR-10 AM TONE RECEIVER

The IR-10 is an AM tone receiver intended for use in remote supervisory control, remote telemetering, and data transmission applications. In response to a received tone within its specified pass-band, the IR-10 produces output contact closures (via relay) or voltage level shifts (via voltage output adapter).

The operating frequency and pass-band of the receiver are determined by a plug-in filter module (IF-10). Each IF-10 bears a number denoting its center frequency (in Hz). This number appears in a front-panel cutout when the filter is installed.

IR-30/IR-30M FSK TONE RECEIVER

The IR-30 is a frequency-shift-keyed (FSK) tone receiver intended for remote supervisory control, telemetry, and data transmission applications. In response to a received MARK, SPACE, or CENTER tone within its specified pass-and, the IR-30 produces output contact closures (via relays) or voltage level shifts (via voltage output adapters).

Receiver operating frequency and pass-band are determined by a plug-in filter module (IF-10)* and a plug-in discriminator (ID-30). The IF-10* bears a number denoting its center frequency (in Hertz). This number appears in a front-panel cutout when the filter module is installed.

When the IR-30 receiver is used in conjunction with an IT-30-3 FSK transmitter, it is modified to slow the release time of the MARK and SPACE output relays. This is necessary because when the MARK and/or SPACE functions of the IT-30-3 are keyed, the resultant output voltage is a series of pulses rather than a continuously keyed voltage. In order to keep the receiver relays energized during the “off” intervals between the pulses received, 250 μf capacitors are connected directly across the coil windings of the MARK and SPACE relays. This modified version of the IR-30 receiver is the model IR-30M.

*Only INIVEN’s unique filter designs reject adjacent channel band-edge transmission frequencies by a minimum of 40 DB, providing maximum attenuation of midpoints between adjacent channels. (See figure for typical filter curves.)

PROGRAMMABLE FSK TONE RECEIVER IR-30P

The IR-30P is a programmable frequency-shift-keyed (FSK) tone receiver intended for use in remote supervisory control, remote telemetering, and data transmission. In response to a received MARK, SPACE or CENTER tone within its specified pass-band, the IR-30P produces outputs of contact closures (via relays) or voltage level shifts (via voltage circuits as an option).

The IR-30P is a completely new design using the latest State-Of-The-Art MSI Technology approach, which provides greater channel flexibility than the conventional designs. System planning and servicing are therefore greatly simplified. This FDM (frequency division multiplex) receiver has a universal card, which is factory or field programmable for any standard channel frequency (see Manual). A new center frequency may be programmed by simply changing the setting of the synthesize program switches or by inserting an appropriate strapfield (see Manual).

Once the center frequency has been selected, the IR-30P operated identically to the traditional IR-30 tone receiver. No modification is required to convert from three-state to two-state operation.

The operating frequencies of the IR-30P receiver are derived from a single crystal oscillator, which provides short and long term reliability with virtually no frequency drift and its related distortion.

A plug-in Channel Derivation Network encompasses an active band-pass filter, discriminator and low pass filter. A different network is needed for each family of channel frequencies. Channel Derivation Networks are available for all popular FDM channel spacing. (See Manual)

As an option, the IR-30P may be modified with a plug-in regenerator, which provides tolerance to transmission distortion up to 46% while its output remains distortion free.

Option IR-30MP: When the IR-30P receiver is used in conjunction with an IT-30-3 FSK transmitter, it must be modified to slow the release time of the MARK and SPACE output relays. This is necessary because when the MARK and/or SPACE functions of the IT-30-3 are keyed, the resultant output voltage is a series of pulses rather than a continuous voltage. In order to keep the receiver relays energized during the “off” intervals between the pulses being received, 220 uf capacitors are connected directly across the coil windings of the MARK and SPACE relays. This modified version of the IR-30P is the model IR-30MP.

*The IR-30P may be modified to a full range of the following outputs:

• IA-11 voltage level output
• IK-2 contact closure output
• IA-20 inverted output
• IAO-2 optical isolated output (open collector or emitter)
• IR-30MP contact closure output

*Please specify one of these options when ordering (see Section 7).

MODEL ISR-12 SCANNER RECEIVER

The INIVEN™ ISR-12 Scanner Receiver operates in conjunction with a standard IR-30 FSK Tone Receiver to receive serial tri-state RTZ data from a remote IST-12 Scanner/FSK Transmitter and convert the data to parallel outputs. The ISR-12 is housed in a standard INIVEN module with 15 LED-indicators mounted on the faceplate. Twelve LEDs are used to display last received status. Two LEDs display Mark and Space data received and one LED indicated the ISR-12 is receiving valid data. The transmission path is via a single 2-wire pair, such as a leased telephone line.

The ISR-12 receives a serial train of pulses via IA-11 voltage output adapters within the IR-30. The ISR-12 verifies this data for proper timing, pulse width, number of pulses, and sync pulse position. If the received data is in satisfactory format, it is gated to the outputs on the terminal block. Outputs can be used to activate lamps, relays, or other user connected loads.

Internal strap options permit the logic level of any point to be inverted. An optional, adjustable scan-fail output is provided.

MODEL IST-12 SCANNER/FSK TRANSMITTER

The INIVEN™ IST-12 Scanner/FSK Transmitter is a 12-point, time division, multiplexing scanner capable of monitoring up to 12 inputs. The IST-12 serializes status data, converts it to FSK tone, and transmits this information to a remote companion ISR-12 Scanner and IR-30 FKS Receiver. The transmission path is via a single 2-wire pair, such as a leased telephone line.

The IST-12 is housed within a standard IT-30 Transmitter chassis. Opto-isolators are used for all status inputs to allow a wide choice of voltage or current sources to activate the inputs with electrical isolation.

IT-10 AM TONE TRANSMITTER

The IT-10 is an AM tone transmitter for use in remote supervisory control, telemetry, and data transmission applications. When keyed by an external contact closure, the transmitter emits an audio tone at the frequency specifies for that particular unit. The keying terminals are located on a terminal block on the rear of the transmitter.

The frequency of transmission is determined by a plug-in oscillator tank circuit module (IO-10). The IO-10 bears a number denoting its resonant frequency (in Hz). This number appears in a front-panel cutout when the module is installed.

FSK TONE TRANSMITTER IT-30/IT-30-3

The IT-30 is a frequency-shift-keyed (FSK) tone transmitter intended for use in remote supervisory control, remote telemetering, and data transmission. The transmitter may be operated in a two-frequency or a three-frequency mode.

In the three-frequency mode, the IT-30 normally transmits a center frequency signal, and may be keyed to transmit either a higher (Mark) frequency or a lower (Space) frequency.

In the two-frequency mode, two types of operation are available:

• Space-hold operation in which the IT-30 normally transmits a Space signal, and may be keyed to transmit a Mark signal.
• Mark-hold operation in which the IT-30 normally transmits a Mark signal, and may be keyed to transmit a Space signal.

The IT-30 may be keyed by either external contacts or by application of voltages to the keying terminals.

The operating frequencies of the IT-30 transmitter are determined by the single plug-in IO-30 module. Each IO-30 module is individually labeled by its center frequency (in Hz). This number also appears in the front-panel cutout of the IT-30 transmitter.

The IT-30-3 transmitter is basically identical to the IT-30 configuration except that a “flasher” (flip-flop) circuit has been added. When both Mark and Space are keyed, the flip-flop circuit keys the transmitter alternately Mark–Space, which activates both relays of the IR-30-M receiver.

FSK TONE TRANSMITTER IT-30/IT-30-3

The IT-30 is a frequency-shift-keyed (FSK) tone transmitter intended for use in remote supervisory control, remote telemetering, and data transmission. The transmitter may be operated in a two-frequency or a three-frequency mode.

In the three-frequency mode, the IT-30 normally transmits a center frequency signal, and may be keyed to transmit either a higher (Mark) or a lower (Space) frequency.

In the two-frequency mode, two types of operation are available:

• Space-hold operation in which the IT-30 normally transmits a Space signal, and may be keyed to transmit a Mark signal.
• Mark-hold operation in which the IT-30 normally transmits a Mark signal, and may be keyed to transmit a Space signal.

The IT-30 may be keyed by either external contacts or by application of voltages to the keying terminals.

The operating frequencies of the IT-30 transmitter are determined by the single plug-in IO-30 module. Each IO-30 module is individually labeled by its center frequency (in Hz). This number also appears in the front-panel cutout of the IT-30 transmitter.

The IT-30-3 transmitter is basically identical to the IT-30 configuration except that a “flasher” (flip-flop) circuit has been added. When both Mark and Space are keyed, the flip-flop circuit keys the transmitter alternately Mark–Space, which activated both relays of the IR-30-M receiver.

PROGRAMMABLE FSK TONE TRANSMITTER IT-30P / IT-30P-3

The IT-30P is a programmable frequency-shift-keyed (FSK) tone transmitter intended for use in remote supervisory control, remote telemetering, and data transmission. The transmitter may be operated in a two-frequency or a three-frequency mode.

The IT-30P provides greatly improved performance, flexibility, and reliability. This FDM (frequency division multiplex) transmitter with a universal card is factory or field programmable for any standard channel frequency (see Manual). A new center frequency may be programmed by simply changing the settings of the synthesizer program switches or by inserting an appropriate strapfield (see Manual).

Once a center frequency has been selected, the IT-30P operated identically to the traditional IT-30 tone transmitter. In the three-frequency mode, the IT-30P normally transmits a center frequency and may be keyed to transmit either a higher (Mark) frequency or a lower (Space) frequency.

In the two-frequency mode, two types of operation are available:

• Space-hold operation in which the IT-30P normally transmits a Space signal, and may be keyed to transmit a Mark signal.
• Mark-hold operation in which the It-30P normally transmits a Mark signal, and may be keyed to transmit a Space signal.

The IT-30P may be keyed by either external contacts or by application of voltages to the keying terminals.

The operating frequencies of the IT-30P transmitter are all derived from a single crystal oscillator providing short and long-term reliability with virtually no keying jitter or frequency drift.

The IT-30P-3 operates identically to the traditional IT-30-3 transmitter. This configuration is basically the same as the IT-30P except that a “flasher” dividing circuit has been added. When both Mark and Space are keyed, the dividing circuit keys the transmitter alternately Mark–Space, which in turn activates both relays of the IR-30-M or the IR-30P-M receiver.

ANALOG TRANSMITTER IAFT-30/IAFT-30A

The INIVEN IAFT-30 is a single analog (4-20 ma typical) to variable frequency (5-25 Hz) transmitter. The IAFT accepts standard current or voltage inputs and outputs a variable operating frequency suitable for transmission over a dedicated standard “voice grade” line.
