Technical Specifications DC discrete output; Isolated output channels; Operating temperature 0~60°C; Short circuit protection on output channels.
Functional Features Output on/off control command to field devices. Channel fault diagnosis. Hot swappable for online replacement. Status feedback to controller.
Application Scenarios Control solenoid valves, motor contactors, alarm lamps in process control system, widely used in petrochemical and power industries.
Performance Parameters Output response time less than 10ms; Each channel has overload protection.
Structural Characteristics Rack pluggable module, terminal block for field output wiring. LED indicators for module status and each channel output state.
Working Principle DCS controller sends digital command via backplane bus. Module internal circuit turns on/off output channel to control field equipment, and feeds back channel health status to controller.
Installation Requirements Install in DCS rack, lock the module. Field output wiring must match load specification. Cabinet grounding is required.
Usage Notes Do not hot swap under power. Check load capacity before connecting field devices. Avoid overloading output channels.
