Data Sheet

Production Specification

The GRV-IACI-12 is an AC digital input module that can sense status from devices such as pumps, fans, and motors that use an 85–140 VAC signal. The 12 channels on this module are isolated from each other (channel-to-channel isolation). The module can sense status from up to 12 devices and offers a full set of features, including:
  • On/off state
  • On/off latching
  • On/off totalization
  • Frequency measurement 
  • Period measurement 
  • Pulse measurement
The GRV-IACI-12 is part of the groov EPIC® system. It mounts on a groov EPIC chassis alongside a GRV-EPIC-PR1 processor and other groov I/O modules (analog, discrete, and serial), to provide the mix of signals you need at a specific location.

NOTE: For projects with simple requirements, see the lower-cost GRV-IACIS-12 module, which provides on and off sensing only.
