GE Fanuc IC670ALG320A Field Control Analog Output Module

The IC670ALG320A is a 4-channel current and voltage source analog output module designed for the GE Fanuc Field Control distributed I/O system. The IC670ALG320A provides four high-precision analog channels that simultaneously deliver current and voltage output signals to drive actuators, valves, and field instrumentation.

Dual Signal Generation and Channel Architecture

Each of the four channels on the module incorporates digital-to-analog (D/A) conversion circuitry configured to drive both current and voltage outputs concurrently. Standard output ranges include 0 to 10 VDC and 4 to 20 mA, with optional jumper configurations on the terminal block allowing expansion to 0 to 12.5 VDC or 0 to 20 mA. Default internal scaling ranges from 0 to 20,000 counts, which can be reconfigured in system software to match custom engineering units.

Galvanic Isolation and Field Wiring Integration

The module logic circuitry is isolated from ground and backplane communications up to 1500 VAC continuous, preventing transient noise propagation. All four output channels share a common 24 VDC external loop supply input (20 to 29 VDC operational range) provided through the Field Control terminal block assembly. The module mounts directly onto a matching Field Control I/O terminal block without requiring tools, supporting keying mechanisms to prevent improper module insertion.

Frequently Asked Questions

Q: How many analog channels does the IC670ALG320A module provide? A: The module provides 4 output channels, with each channel delivering simultaneously available current and voltage outputs.

Q: Can the voltage output range be expanded beyond 0 to 10 VDC? A: Yes, adding a physical jumper configuration on the underlying I/O terminal block extends the default 0–10 VDC voltage range to 0–12.5 VDC.
