Woodward 9908-354 Thermocouple Input Module

Product Brief Introduction The Woodward 9908-354 thermocouple input module acquires millivolt thermoelectric signals from thermocouples. It performs cold junction compensation and signal linearization to provide reliable high-temperature measurement data.
Tag:

Technical Specifications 24VDC power supply, multi-channel thermocouple input, built-in automatic cold junction compensation. Operating temperature: -40℃ ~ +70℃.

Functional Features Thermocouple signal conditioning, cold junction compensation, burnout detection, temperature data upload.

Application Scenarios Engine exhaust temperature monitoring, gas turbine combustion zone temperature measurement, high-temperature pipeline monitoring.

Performance Parameters Wide measuring range, fast signal response, automatic correction of cold junction error.

Structural Characteristics Rack pluggable module, channel fault and running status LED indicators.

Working Principle Weak thermoelectric voltage from thermocouple enters the conditioning circuit. After compensation and linear calculation, the module converts voltage signal into actual temperature value.

Installation Requirements Use matched thermocouple compensation cables, separate compensation wires from power cables.

Usage Notes Do not mix different thermocouple types, check wiring polarity before power on.
