Technical Specifications 24VDC auxiliary power, multi-channel 4-20mA isolation transmission. Operating temperature: -40℃ ~ +70℃, high isolation voltage.
Functional Features Current signal isolation transmission, ground loop suppression, signal filtering, overvoltage protection.
Application Scenarios Long-distance analog signal transmission, sites with serious ground potential drift.
Performance Parameters High signal linearity, small transmission error, strong common-mode interference rejection.
Structural Characteristics DIN rail mounting board, independent isolation circuit for each channel.
Working Principle Field side 4-20mA signal is transmitted through isolation components. There is no direct electrical connection between field side and control side to cut off ground loop current.
Installation Requirements Install close to the I/O terminal block, separate isolated signal cables from AC power cables.
Usage Notes Calibrate zero and span after installation, do not mix isolated and non-isolated loops.
