- channel-to-channel isolation
The GRV-ITMI-8 analog module is part of the groov EPIC® system. This flexible module provides 8 channels of input from millivolt or thermocouple field devices. Each channel is individually configurable for ±1200 mV, ±600 mV, ±300 mV, ±150 mV, ±75 mV, ±50 mV, ±25 mV or Type B, E, J, K, N, R, S, or T thermocouples.
The eight channels on the module are isolated from each other. Since these channels do not share any common connections, you can use grounded sensors and field devices with them.
The GRV-ITMI-8 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.
