Technical Specifications 24VDC power supply, multi-channel isolated 4-20mA analog output. Operating temperature: -40℃ ~ +70℃, built-in short-circuit protection.
Functional Features Digital-to-analog conversion, current signal output, output value tracking, loop fault detection, output limiting.
Application Scenarios Auxiliary valve continuous adjustment, remote indicator signal transmission, analog signal output to DCS.
Performance Parameters High output linearity, low ripple, fast response to command change, stable current output.
Structural Characteristics Rack pluggable module, output channel status indicator lights.
Working Principle The module receives target value from main controller through internal bus, converts digital value into 4-20mA analog current signal and sends the signal to field equipment to realize continuous adjustment.
Installation Requirements Use shielded cables for analog output loops, confirm load impedance within the allowable range.
Usage Notes Do not short-circuit output terminals, check loop continuity during routine maintenance.
