Module 8 kênh đầu vào nhiệt Thermistor + 8 kênh đầu ra số DO ICP DAS I-87005W

Features

  • Thermistor Input

  • Individual Channel Configuration

  • Open Wire Detection

  • 8-channel Digital Output for Alarm Output

  • 3000 VDC Intra-module Isolation

  • Overvoltage Protection for Thermistor Input

  • User-defined Thermistor Types

  • Wide Operating Temperature Range: -25 ~ +75°C

Introduction

The I-87005W module is used for measuring temperature using a thermistor. The module supports a wide range of thermistors, and features individual channel configuration, which means that eight of the input channels can be individually configured for different kinds of thermistor. In addition, the I-87005W also provides 8 digital output channels that can be used for alarm output, and supports user-defined thermistor types, which can be added by specifying the Steinhart coefficients, if necessary. The inclusion of 3000 VDC intra-module isolation and overvoltage protection for the thermistors on the I-87005W ensures that the module operates at a higher reliability.
