tM-AD5C

5-channel Isolated Current Input Module

Introduction

The tM-AD5C is an analog input module that includes 5 differential analog input channels and provides a programmable input range on all analog inputs (+/- 20 mA, 0 ~ 20 mA, 4 ~ 20 mA). The sampling rate of the tM-AD5C is adjustable and is available in either fast or normal mode and It also provides 4 KV ESD protection as well as 2500 Vrms intra-module isolation.
