Technical Specifications 24VDC power supply, 4-20mA loop power and signal conditioning. Operating temperature: -40℃ ~ +70℃.
Functional Features Transmitter loop power supply, current signal filtering, signal protection, open transmitter detection, fault output.
Application Scenarios Pressure, flow and temperature transmitter signal matching in generator and turbine control cabinets.
Performance Parameters Stable loop power, low signal attenuation, reliable open-circuit diagnosis.
Structural Characteristics Compact interface PCB board, channel power and fault indicator lights.
Working Principle The board supplies excitation power to two-wire transmitters on the same signal cable, filters the 4-20mA current signal, and sends conditioned signal to the analog acquisition module.
Installation Requirements Mount near the transmitter terminal row, shielded signal cable is required.
Usage Notes Confirm the transmitter is two-wire type before wiring, avoid short-circuit on signal loop.
