Module RS-485 Modbus RTU 8 kênh đầu vào nhiệt (Thermistor) ICP DAS tM-TH8 CR

Features

  • 8-channel Thermistor Input
  • User-defined Thermistor Types
  • Dual Watchdog

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 thermistors 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.

Applications

  • Industrial Automation
  • Industrial Machinery
  • Building Automation
  • Food and Beverage Systems
  • Semiconductor Fabrication
  • Control Systems
