IO975: Thermocouple Simulation I/O Module 

Accurate low-voltage source module capable of simulating up to 32 thermocouples, with Simulink® driver blocks

The IO975 I/O module is a low voltage analog output module and an ideal solution for simulating most thermocouple types and performing ECU testing. Each channel supports accurate output voltages up to +/-100 mV and resolutions down to 0.7 uV, to best meet your applications.

The isolation from ground and the two wire outputs ensure accurate thermocouple simulation even in the presence of common mode voltages in the system. This module also features independent cold junction connections allowing it to be connected to multiple references.

The IO975 is available with accurate 8, 16, 24 or 32 isolated two-wire output channels, and can be directly connected to the thermocouple measurement system. No calibration is required.

Key features

  • 8, 16, 24 or 32 low-voltage source channels, ideal for thermocouple simulation
  • ±20 mV (0.7 uV resolution), ±50 mV (1.7 uV resolution) ±100 mV (3.3 uV resolution) output voltage ranges
  • Two-wire output for each channel (Vout – Vcold)
  • Independently isolated channels
