Data Sheet

Production Specification

Part of the groov EPIC® system, the GRV-IMA-24 analog input module is part of the groov EPIC® system. This module provides 24 channels of analog current input with an input range of ±20 mA, 0–20 mA, and 4–20 mA. Ranges are software configurable.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-IMA-24 mounts on a groov EPIC chassis with other analog, discrete, and serial groov I/O modules and a GRV-EPIC-PR1 processor. 

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.

Opto Products, like GRV-IMA-24, are ideal for OEMs and machine designers, process control, machine monitoring, power and energy monitoring, predictive maintenance, remote installations like water-wastewater and oil & gas, SCADA, and industrial internet of things applications.
