Application Scenarios
Ideal for high-temperature measurement applications such as boiler furnaces, reactors, and exhaust pipes.

Performance Parameters

  • Isolation: High-impedance isolation between channels and bus.
  • Response: Rapid state change capture for sequential control.
  • Rating: IP20 protection

Material Composition
Flame-retardant industrial housing with high-reliability amplifier circuits. Gold/tin-plated copper terminal blocks ensure long-term connection integrity.

Structural Characteristics
Standard fieldbus form factor with clear channel silk-screen printing and LED status indicators. Precision backplane connector for secure mounting.

Working Principle
Thermocouple mV signals are amplified and converted via Sigma-Delta A/D, combined with cold junction compensation, and linearized according to thermocouple tables before transmission.

Installation Requirements
Use dedicated thermocouple extension wire or shielded twisted pair. Shield must be grounded at cabinet side only.

Precautions for Use
Verify thermocouple polarity and type match software configuration. Never apply voltage or current signals to this module.
