Introduction

The tM-TH8 is an 8-channel isolated thermistor input module that can be used for measuring temperatures via a thermistor. Many types of thermistor are supported and user-defined types can be added by specifying the Steinhart coefficients, if necessary. The added 2500 VDC intra-module isolation and 120 VDC overvoltage protection for the thermistor on the tM-TH8 ensure that the module will operate with higher reliability.
