Description

Product Description

The IC200ALG326 is a compact analog output module from the GE Fanuc VersaMax platform, engineered to deliver stable current signals for industrial control applications. It provides eight single-ended output channels grouped under a common reference, designed for driving field devices such as control valves, variable speed drives, and actuators.

This module operates in current-sourcing mode and supports both 4–20 mA and 0–20 mA output ranges, selectable via onboard jumper configuration. With a 13-bit resolution, it ensures consistent signal scaling suitable for most process control environments.

Integrated diagnostics monitor both field and backplane power conditions, while configurable output fallback behavior allows the system to maintain stability during communication interruptions or power loss. The module can be replaced under power (hot insertion), though careful handling is recommended to avoid disturbances on the I/O rack.

FAQ

Q: Are the outputs isolated individually?
A: No, all eight channels share a common reference and are not individually isolated.

Q: Can the output range be changed without software?
A: Yes, switching between 4–20 mA and 0–20 mA is done via a hardware jumper.

Q: What happens if communication with the PLC is lost?
A: The module can be configured to either hold the last output value or transition to a predefined safe state.
