Technical Specifications 24VDC power supply, multi-channel isolated 4-20mA analog output. Operating temperature: -40℃ ~ +70℃, adjustable output range.
Functional Features Digital-to-analog conversion, analog signal output, output value tracking, circuit short-circuit protection, fault diagnosis.
Application Scenarios Auxiliary valve positioning control, remote indicator transmission, DCS analog signal output interface.
Performance Parameters High output linearity, small output ripple, fast response to command changes, stable current output.
Structural Characteristics Rack pluggable module, output channel status indicator lights, built-in output protection circuit.
Working Principle The module receives target output values from the main controller over the internal bus. It converts digital values into corresponding 4-20mA current signals and sends them to field equipment to realize continuous adjustment and remote indication.
Installation Requirements Use shielded cables for analog output wiring, avoid long-distance wiring without signal amplification.
Usage Notes Check load impedance of each output loop, do not short output terminals.
