Working Principle
The main controller sends digital switch commands to the module through the system bus. The internal drive circuit controls the pull-in and disconnection of electromagnetic relays. The relay contacts output switch signals to control the start, stop and switching of field electrical equipment. Meanwhile, the module feeds back contact status to the controller.
Advantage Highlights
- High reliability industrial relay, long service life
- Complete electrical isolation, high system safety
- Independent channel protection, single channel fault does not affect the whole module
- Intuitive status indication, easy for on-site inspection
Applicable Industries
Turbine auxiliary equipment control, power plant switch control, industrial equipment start-stop control, safety interlock control system
Installation Requirements
- Rack installation in standard industrial control cabinet
- Load wiring must match relay contact rated parameters
- Keep away from high-temperature heat sources
- Ensure good ventilation for heat dissipation
Usage Notes
- Do not exceed the rated voltage and current of relay contacts
- Forbid frequent rapid switching beyond the working frequency range
- Regularly check contact wear and wiring tightness
- Use surge absorption components for inductive loads
