Description

Product Description

The IC220ALG220 analog input module is part of the GE Fanuc VersaPoint distributed I/O family, engineered for accurate acquisition of industrial analog signals. It provides two independently configurable input channels capable of measuring both voltage and current, making it suitable for a wide range of field instrumentation.

With 15-bit resolution and a fast update cycle, the module ensures precise signal conversion for control and monitoring tasks. It supports typical industrial transmitters, including 2-wire loop-powered and 3-wire active sensors. Each channel can be configured separately, allowing mixed signal types within the same module.

The unit interfaces with field wiring through a dedicated terminal base, typically IC220TBK061 (in some system configurations, IC220TBK062 may also be referenced depending on wiring scheme), which must be ordered separately.
