IC694ALG223CA

The GE Fanuc IC694ALG223CA is a high-precision 16-channel Analog Input Module designed for the PACSystems RX3i Series. Built for demanding industrial automation applications, this module provides accurate and stable analog signal measurement for current-loop devices such as transmitters, sensors, actuators, and process instruments.

The module supports 1 to 16 selectable single-ended input channels, offering flexibility for a wide range of control and monitoring tasks. Each channel supports multiple current input ranges—0–20 mA, 4–20 mA, and Enhanced 4–20 mA—making it suitable for standard industrial analog signals used in process automation, machine control, and data acquisition systems.

With an impressive update rate of 13 ms across all 16 channels, the IC694ALG223CA ensures fast and responsive input processing for real-time applications. Its 19 Hz low-pass filter, 250-ohm input impedance, and >80 dB cross-channel rejection deliver high signal integrity while minimizing electrical noise, interference, and cross-talk between channels.

Designed for reliability and operational efficiency, the module operates using an external 20–30 VDC supply and consumes just 120 mA from the 5V backplane bus. Its rugged build and industrial-grade design allow it to perform consistently in harsh environments, making it a dependable solution for manufacturing, energy, utilities, robotics, and process control industries.
