Product Description

GL7-M, 10-ch, voltage thermocouple and RTD amp, high isolation per channel, 100 samples/s to 1 sample/h, 20mV to 50V F.S. and 1-5V F.S.

Isolated universal 10 channel temp/voltage multi-input module for thermocouple, RTD, and scaled voltage input signals.  For mixed used testing and monitoring environment requiring multi-various physical measurement data, GL7-M functions as a very useful data platform solution.  Max 10 modules per main unit GL7000.  10ms (100 samples/sec) sampling interval can be achievable for all 10 units (100 channels) and synching together up to 5 GL7000 units with 10 modules each for a maximum 500-channel system.  Max input voltage range is 60Vp-p.
