The IC200ALG322D (IC200ALG322) is a high-precision 4-channel analog output module from the GE Fanuc VersaMax series. Designed for industrial process control, it provides 4 to 20 mA current loop outputs to drive actuators, valves, and VFDs. The "D" revision enhances thermal performance and component longevity while remaining fully compatible with previous IC200ALG322 modules.
With 12-bit resolution, the IC200ALG322D ensures smooth and granular control over process variables. Each channel includes open-wire detection and loop power monitoring for proactive fault diagnostics. Its compact footprint allows high-density installation on standard VersaMax carriers, while the module draws internal logic power from the backplane and requires external 24V DC for output loops.

Mount on an IC200CHS series carrier.
Use shielded twisted-pair cabling to maintain 12-bit precision.
LED indicator signals normal operation (green) or alerts (amber/off) for loss of 24V field power or hardware faults.
Does the IC200ALG322D support voltage outputs (0–10V)?
No. This module is strictly a 4–20 mA current output. Voltage output requires a different module (e.g., IC200ALG321) or an external 500 Ω resistor for current-to-voltage conversion.
What happens if a field wire is broken?
The module detects open-wire conditions and reports a "Low Scale" or "Open Wire" fault to the CPU, enabling immediate maintenance intervention.
