GE Fanuc IC694ALG223

The IC694ALG223 is an Analog Current Input Module designed for integration within GE Fanuc's RX3i PACSystems. This module features 16 channels of single-ended inputs, which can be configured through the provided software to operate within three distinct input ranges: 4 to 20 mA, 0 to 20 mA, or an enhanced 4 to 20 mA range. Each input channel allows for high and low alarm limits, making it ideal for monitoring critical parameters. Notably, in the enhanced mode, the module can detect current levels as low as 0 mA, facilitating open-wire fault detection for 4 to 20 mA signals.

Engineered to communicate with the CPU, the IC694ALG223 can relay module status and external power conditions through designated program reference addresses. It draws 120 mA from the 5 VDC bus on the PLC backplane and requires an additional 65 mA plus the loop current from a user-supplied 24 VDC power source. The onboard MODULE OK LED provides real-time status updates during power-up, indicating operational readiness, power issues, or configuration problems based on its state. The User Supply LED confirms the integrity of the external 24 VDC supply.

Configurable parameters for the IC694ALG223 include active channel selection, input data reference addresses, input length and range settings, alarm thresholds, and I/O scan settings. This module operates effectively within an ambient temperature range of 32 to 140 degrees Fahrenheit, supporting up to a maximum input circuit current of 65 mA. The input filter response is optimized at 200 Hz, ensuring high-performance signal processing.

Overall, the IC694ALG223 represents a versatile and robust solution for industrial automation applications requiring precise analog current input capabilities.
