GE IC670ALG320K
Product Name: GE Fanuc Field Control Analog Output Module (IC670ALG320)
Introduction: The IC670ALG320 (with suffix K) is a 4-channel analog output module designed for the GE Fanuc Field Control I/O system. It converts digital control signals from a host processor into precise analog current or voltage outputs for controlling industrial actuators, valves, dampers, and positioners. (Note: The “K” suffix designation specifics are not detailed in available public documentation; the base IC670ALG320 specifications are provided.)

Functional Features:
- Four independent sourcing channels for current or voltage output
- Configurable output ranges via external jumper links or internal registers
- Integrated EMI filtering and ground isolation
- Front-panel LED indicators for monitoring field power and backplane bus status
- Single-ended wiring for simplified integration
Structural Characteristics: The module is a Field Control I/O module with 4 channels grouped as a single group, designed for DIN-rail or rack mounting in the Field Control system.
Working Principle: The module receives digital signals from the host processor via the Bus Interface Unit (BIU), converts them to analog values using a 12-bit DAC, and sources the current/voltage to field devices.
Installation Requirements:
- Ensure system power is disconnected before installing or removing
- Use instrumentation-grade shielded twisted-pair cabling
- Verify external 24 VDC power supply is within 20-29 VDC range
- Configure output ranges using jumper settings before applying power
- Maintain proper ventilation (dissipation up to 4.3 W)
Usage Notes: Compatible with Field Control and Rx7i PACSystems architectures. Install in a clean, dry environment free from conductive dust and liquid ingress.
