Technical Specifications 24VDC power supply, multi-channel 4-20mA isolated current output. Operating temperature: -40℃ ~ +70℃.
Functional Features Digital-to-analog conversion, stable current output, output loop fault diagnosis, short-circuit protection.
Application Scenarios Valve position control, remote analog meter driving, auxiliary equipment proportional adjustment.
Performance Parameters Good output linearity, small temperature drift, stable driving capacity for field loads.
Structural Characteristics Rack pluggable module, channel running and fault LED indicators.
Working Principle The module receives digital command data from backplane bus, converts the value into proportional 4-20mA current signal and outputs to the field control loop.
Installation Requirements Confirm the load resistance range of field devices before powering on, shielded wiring is recommended.
Usage Notes Avoid long-time short circuit of output terminals, test output accuracy regularly.
