I-87005W-G
8-ch Thermistor Input and 8-ch DO Module
Features
• Thermistor Input
• Individual Channel Configuration
• Open Wire Detection
• 8-channel Digital Output for Alarm Output
• Overvoltage Protection for Thermistor Input User-defined Thermistor Types
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.
Applications
• Temperature Measurement
• Environment Monitoring
• Tunnel Monitoring
