Technical Specifications 24VDC power supply, multi-channel isolated 4-20mA current output. Operating temperature: -40℃ ~ +70℃.
Functional Features Digital-to-analog conversion, stable current output, output loop fault diagnosis, short-circuit protection.
Application Scenarios Proportional valve adjustment, remote analog indicator driving, auxiliary equipment closed-loop regulation for prime mover control systems.
Performance Parameters Excellent output linearity, low temperature drift, stable load driving capacity.
Structural Characteristics Rack pluggable module, channel running and fault LED indicators.
Working Principle The module receives digital command data transmitted via the backplane bus, converts the value into a proportional 4-20mA current signal and sends it to the field control loop.
Installation Requirements Confirm the load resistance range of field devices before powering on, shielded twisted-pair cables are recommended.
Usage Notes Avoid long-time short circuit of output terminals, test output accuracy regularly during maintenance.
