Product Overview

The GE Fanuc IC694ALG223A is a high-density current sensing interface for the PACSystems RX3i platform. This module offers 16 single-ended channels to monitor 0–20 mA, 4–20 mA, and 4–20 mA Enhanced signals from industrial transmitters. It converts these analog signals into digital data for the RX3i CPU, enabling precise monitoring of flow, pressure, and level in process control loops. We supply this unit as 100% Brand New original equipment to ensure optimal performance and reliability in your automation systems.

Technical Specifications

Engineering Advantages

• High-Density Monitoring: The IC694ALG223A accommodates 16 channels in a single slot, reducing module count, lowering hardware costs, and saving valuable rack space in control cabinets.

• Enhanced Signal Diagnostics: The 4–20 mA Enhanced range provides out-of-range values, helping the CPU detect low process signals or hardware faults, such as a wire break or failed transmitter, speeding up troubleshooting.

• Advanced Optical Isolation: Protects the RX3i backplane from electrical surges up to 1500 VAC, preventing damage from external ground loops or wiring errors.

• Rapid Data Refresh: With a 13 ms update rate, the module ensures near real-time data for PID loops in fast-reacting processes, such as chemical blending or hydraulic systems.

• Effective Noise Rejection: The integrated 19 Hz low-pass filter and 80dB cross-channel rejection suppress high-frequency noise, ensuring stable and clean data input, even in noisy environments with VFDs and motors.

FAQs

Does this module support voltage inputs (e.g., 0-10V)?

No, the IC694ALG223A is a dedicated current input module. For voltage sensing, you will need a different module, such as the IC694ALG220 or ALG221.

Is this a brand new or refurbished module?

We guarantee this IC694ALG223A is 100% Brand New. It comes in original factory-sealed packaging and has no previous field operation hours.

Can I configure each channel for a different range?

Yes, you can configure each channel independently to accept different input ranges (0–20 mA, 4–20 mA, or 4–20 mA Enhanced) using the PAC Machine Edition software.

What happens if a field wire breaks in the 4-20 mA mode?

In 4–20 mA mode, a broken wire results in a 0 mA signal, which the module reports as a "Low Alarm" or under-range value. In Enhanced mode, the module provides more detailed data to help identify the open-circuit condition.
