The IC694ALG221 is a component module of the PACSystem RX3i Programmable Automation Controller (PAC). The module has four (4) analog input channels designed to accept current input signals, such as 0-20 mA and 4-20 mA electrical standards. The module is used to connect analog measuring instruments such as transmitters, signal splitters, isolators, converters and similar devices for monitoring and closed-loop control of analog systems. The IC694ALG221 has a built-in analog-to-digital converter (DAC) circuit that converts analog data into a digital format that can be read by the host controller for processing, conditioning, and integration into user logic. The ADC output has a resolution of 4 μA at 4-20mA and 5 μA at 0-20 mA, with an absolute accuracy of 0.1% full scale +0.1% reading. The update rate is 2 ms per input channel, factory-calibrated to 4 μA per count. The module has a common mode voltage of 200 volts and linearity of < 1 least significant bit (LSB). It has field-to-backplane (optical) isolation and frame-ground isolation with continuous voltages of 250 VAC and 1500 VAC for 1 minute. The module has an input filter response of 325 Hz and an input impedance of 250 Ω. The module has an internal power rating of 100 mA (isolated 24 VDC power supply) and 25 mA (+5VDC bus on the PLC backplane). The MODULE comes with a MODULE OK LED, provided the user indicates that the module is actively powered.

The GE Fanuc IC694ALG221 input module is an analog current input module with 4 input points. It is compatible with every CPU manufactured in the GE RX3i PacSystems product line. The module is hot-swappable, meaning it can be plugged in or pulled out of a powered GE backplane. Attempts to hot-swap the IC694ALG221 input module may result in component damage and user injury.

GE Fanuc RX3i PacSystems IC694ALG221 4-point analog draw current from the backplane. At 5 volts DC, the analog input module can support loads of 25 mA or 0.125 watts. At 24 volts DC isolation, the input module can support a load of 100 mA or 2.4 watts. The IC694ALG221 input module can also operate in 2 different input current ranges of 4 to 20 mA and 0 to 20 mA. The module comes with a range jumper for input channels 1 and 2, and another range jumper for input channels 3 and 4. The conversion speed for each channel is half a millisecond. There is a green LED on the module, called the module normal LED, which lights up when the module is powered on.
