The GRV-IACIS-12 AC digital input module provides input status from devices such as pumps, fans, and motors that use a 85–140 VAC signal. The module has 12 channels with channel-to-channel isolation. Each channel provides on or off sensing only.
Part of the
groov EPIC
® system, the GRV-IACIS-12 mounts on a
groov EPIC chassis with a
GRV-EPIC-PR1 processor and
groov I/O modules (discrete, analog, and serial).
NOTE: For projects with more complex requirements, see the
GRV-IACI-12 module, which provides additional features (latching, totalization, and more).
