GRV-ITM-12

$675.00 (USA and Canada only)

Availability: In stock
Analog input, 12 channels, thermocouple or mV

Production Specification

The GRV-ITM-12 analog module is part of the groov EPIC® system. This analog module provides 12 channels of input from millivolt or thermocouple field devices. There is no isolation between channels; however, the 12 channels are divided into two zones, with one zone isolated from the other zone.

The GRV-ITM-12 mounts on a groov EPIC chassis with a GRV-EPIC-PR1 processor and additional analog, discrete, and serial groov I/O modules, to provide the mix of signals you need at any location.
