I-87005W-G CR 8-ch Thermistor Input and 8-ch DO Module (RoHS)

THÔNG TIN SẢN PHẨM

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 vUser-defined Thermistor Types
• RoHS Compliant
• 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.

Application

• Temperature Measurement
• Environment Monitoring
