Data Sheet

Production Specification

Part of the groov EPIC® system, the GRV-IAC-24 is an AC input module that can sense the status from devices such as pumps, fans, and motors that use a 85–140 VAC/VDC signal. The module cover includes an LED that indicates status and a touch-sensitive pad. Touch the pad and the groov EPIC processor displays information about the module, including specifications and a wiring diagram.

The GRV-IACHV-24 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 or GRV-EPIC-PR2 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.

All groov I/O modules are UL/cUL listed and compliant with the ATEX, Low Voltage, and EMC CE and UKCA directives. Each module is factory tested twice before shipment and most modules are guaranteed for life.
