Description

Product Description

The IC220ALG320 is a single-channel analog output module from the GE Fanuc VersaPoint I/O family, intended for precise control of field devices in distributed automation systems. It converts digital control values into stable analog signals, supporting both voltage and current output modes.

Designed for accuracy and responsiveness, the module features 16-bit digital-to-analog conversion and sub-millisecond update performance. It is suitable for driving actuators such as control valves, variable speed drives, and positioning devices where signal fidelity is critical.

The module operates using a 2-wire connection method and interfaces with field wiring via the IC220TBK203 terminal base, which must be ordered separately. Integrated LED indicators provide immediate visual feedback on operating status and output activity.

FAQ

Q: Can voltage and current outputs be used at the same time?
A: No, the module supports either voltage or current output per configuration, not both simultaneously.

Q: What terminal base is required for installation?
A: The module requires the IC220TBK203 terminal strip for field wiring.

Q: Is the module suitable for long-distance signal transmission?
A: Yes, but proper shielding and grounding practices should be followed to maintain signal integrity.
