Technical Specifications Multi-channel temperature input; Support RTD and thermocouple; Intrinsic safety protection; Galvanic isolation; DIN rail mount; Operating temperature -40°C ~70°C.
Functional Features Multiplex multiple temperature sensor signals. Intrinsic safety energy limiting for hazardous side. Isolation noise suppression. Built-in sensor wire break detection.
Application Scenarios Oil, gas and chemical industries, multi-point temperature measurement in reactors, pipelines and furnaces in explosive hazardous zones.
Performance Parameters High temperature measurement accuracy; Low signal crosstalk between channels; Meet ATEX intrinsic safety requirement.
Structural Characteristics DIN rail mounted module, multi-channel terminal blocks for field temperature sensors, LED indicators for power, communication and fault.
Working Principle The module scans each connected RTD or thermocouple channel sequentially, converts temperature value to digital signal. Isolation circuit separates hazardous field side and control room side, while limiting energy to meet intrinsic safety standard.
Installation Requirements Install on DIN rail in safe cabinet. Use dedicated shielded temperature cable for field sensors. Separate sensor wiring from power cables.
Usage Notes Configure sensor type in system software before commissioning. Verify intrinsic safety certificate matching. Check wire break alarm function regularly.
