Technical Specifications 24VDC auxiliary power, multi-channel 4-20mA signal isolation. Operating temperature: -40℃ ~ +70℃, high isolation voltage.
Functional Features Current signal isolation transmission, ground loop suppression, signal filtering, overvoltage protection.
Application Scenarios Pressure, flow and level transmitter signal isolation, long-distance analog signal transmission.
Performance Parameters High signal linearity, low transmission error, strong rejection of common-mode interference.
Structural Characteristics DIN rail mounting board, each channel equipped with independent isolation circuit.
Working Principle The 4-20mA signal from the field side is converted and transmitted through isolation components. There is no direct electrical connection between the field side and control side to cut off ground loop current.
Installation Requirements Install near the I/O terminal base, keep isolated signal cables away from AC power cables.
Usage Notes Calibrate signal zero and span after installation, avoid mixing isolated and non-isolated current loops.
