Technical Specifications 24VDC power supply; multiple isolated analog output channels; built-in channel short-circuit protection; signal isolation design. Operating temperature -40℃ ~ +70℃.
Functional Features Digital-to-analog conversion, output signal scaling and adjustment, real-time channel status monitoring, short-circuit fault detection and alarm.
Application Scenarios Turbine and gas engine control system, analog actuator drive and valve positioner control loops.
Performance Parameters High conversion precision, low long-term signal drift, stable analog output under varying load impedance.
Structural Characteristics Compact DIN rail installation housing, pluggable terminal connectors, neatly arranged internal circuit layout.
Working Principle Receive digital setpoint instructions sent by main controller. The module executes digital-to-analog conversion and outputs standard 4-20mA or voltage analog signals to control field actuators and valve positioners.
Installation Requirements Install in dust-proof control cabinet; use shielded twisted pair cable for analog output wiring.
Usage Notes Check the load impedance of each output channel before commissioning; prevent short-circuit of output terminals.
