ICPDAS Analog Input Module tM-TH8 is 8 channels module used for measuring temperature by the thermistor. It supports many kinds of thermistors and user-defined types by specifying the Steinhart coefficients to add other thermistors, if necessary. Adding 2500 Vrms intra-module isolation and overvoltage protection for thermistor on tM-TH8 makes itself running with higher reliability.
