Model: I-87005W
8-channel thermistor input and 8-channel digital output module


I-87005W-G is used for measuring temperature by the thermistor. It supports many kinds of thermistors and features individual channel configuration which means that eight of its input channels can individually be configured with different kind of thermistor. Besides, I-87005W-G also has 8-channel digital outputs for alarm output, if necessary. Adding 3000 VDC intra-module isolation on I-87005W-G makes itself running with higher reliability.
  • Support Thermistor Input
  • Individual Channel Configuration
  • 8-channel Digital Outputs for Alarm Output
