ICPDAS tM-TH8 8-channel Isolated Thermistor Input Module with High Voltage Protection ● 8-channel ● Thermistor Inputs ● 120 VDC Overvoltage Protection ● Resolution: 16-bits ● User-Defined ● 4 kV ESD and EFT Protecton ● 3 kV Surge Protection ● Dual Watchdog ● 2500 VDC Intro-module Isolation ● Cost-effective ● Wide Operating Temperature Range: -25 °C ~ +75 °C
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.
APPLICATIONS: ● Industrial Automation ● Industrial Machinery ● Building Automation ● Food and Beverage Systems ● Semiconductor Fabrication ● Control Systems
