Overview Manuals Technical notes Product Applications Installation and Wiring Instructions

Features:

  • 4–Channel Analog Current Input
  • 4 to 20 mA
  • PACSystems RX3i System
The IC694ALG221 is a PACSYstem RX3i Programmable Automation Controller (PAC), analog input module. This module is formerly manufactured by GE.This module features Four (4) analog inputs individually configurable to receive current signals specifically, 0-20 mA and 4-20 mA with a resolution of 4 µA at 4-20mA and 5 µA at 0-20 mA.

The GE Fanuc RX3i PacSystems IC694ALG221 4-point analog draw current from the backplane. At 5 Volts DC, this analog input module can support a load of 25 milliamps or 0.125 Watts. At 24 Volts DC isolated voltage, this input module can support a load of 100 milliamps or 2.4 Watts. The IC694ALG221 input module can also operate with 2 different input current ranges which are 4 to 20 milliamps and 0 to 20 milliamps. This module comes with a range jumper for input channels 1 and 2, and another range jumper for input channels 3 and 4. Every channel has a conversion speed of half a millisecond. There is 1 green LED on the module known as the Module OK LED that lights up when the module is powered on.

The IC694ALG221 GE Analog Input Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
GE IC694ALG221 Analog Input Module Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Two range jumpers are provided with Module; one for channelsone and two, and the other for channels three and four.Conversion speed for each of the four channels is one–halfmillisecond. This provides an update rate of two milliseconds forany channel. Resolution of the converted signal is 12-bit binary(1 part in 4096) over either range.Input protection for Module is sufficient for operation withreduced performance with up to 200 V common–mode. Moduleprovides electrical isolation of externally generated noise betweenfield wiring and the backplane through the use of optical isolation.This module can be installed in any I/O slot of an RX3i system.Module does not support insertion into or removal from an RX3iUniversal Backplane which is under power (see Hot Insertion andRemoval Not Supported
  • Smart Home/Building Automation:Sensor input for sophisticated environmental control
  • Environmental Monitoring:Analyzes gas, humidity & temp sensor data
  • Pharmaceutical Manufacturing:Precise monitoring for stability & compliance
  • Food Processing:Regulates temp, flow & pressure for quality/safety
  • Petrochemical Industry:Monitors pressure, temp & levels for safety/efficiency

Backplane: Can be installed in any I/O slot of an RX3i Universal or Expansion backplane.
Power Requirement: Requires an external 24 VDC source connected via terminal TB1 on the left side of the backplane if installed in a Universal Backplane.
Wiring: Connect field devices to the module terminal block. Use shielded, twisted-pair cable to reduce noise.
Ranges: The module is configured for 4-20mA (default) or 0-20mA using two range jumpers (one for channels 1-2, one for channels 3-4).

FAQs

  • What is the IC694ALG221?

    +
    The GE IC694ALG221 is a 4-channel, differential, analog current input module for the PACSystems RX3i series (also compatible with Series 90-30). It converts analog current signals (0-20mA or 4-20mA) into digital data.
  • How many channels does IC694ALG221 have?

    +
    It has 4 differential current input channels.
  • What power supply does IC694ALG221 require?

    +
    It requires a 24VDC power supply, typically connected to the TB1 terminal block.
  • How do I configure the ranges?

    +
    The module uses two jumpers to set ranges: one for channels 1 and 2, and one for channels 3 and 4. Connecting a jumper to the I/O terminal panel sets the corresponding channels to 0-20mA.
