OPTO 22 - GRV-IMAI-8 _ SOURCING 8 CHANNEL mA INPUT

Quick Specs:

SOURCING 8 CHANNEL mA INPUT

The GRV-IMAI-8 analog input module is part of the groov EPIC^® system. This module provides channel-to-channel isolation on its 8 channels of analog current input with an input range of 0 to 20 mA and 4 to 20 mA. Each channel can be powered by an internally isolated loop supply or from an externally connected loop supply. Ranges are software configurable.

The GRV-IMAI-8 mounts on a groov EPIC chassis with other analog, discrete, and serial groov I/O modules and a GRV-EPIC-PR1 processor.
