AC discrete input, 24 channels, 85-140 VAC

Production Specification

The GRV-IAC-24 is a groov EPIC® system AC input module that can sense the status from devices such as pumps, fans, and motors that use a 85–140 VAC signal. It can sense status from up to 24 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-IAC-24 module mounts on a groov EPIC chassis alongside a GRV-EPIC-PR1 processor and other analog, discrete, and serial groov I/O modules.

NOTE: For projects with simple requirements, a lower-cost option is the GRV-IACS-24 module, which offers only on and off sensing.
