Data Sheet

Production Specification

Part of the groov EPIC® system, the GRV-ITMI-8 analog module is flexible. This module provides 8 channels of input from millivolt or thermocouple field devices. Each channel is individually configurable for ±1200 mV, ±600 mV, ±300 mV, ± and 150 mV, ±75 mV, ±50 mV, ±25 mV or Type B, E, J, K, N, R, S, or T thermocouples. 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 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.

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-ITMI-8, 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.
