Function and Working Principle
The 5441-645 Relay Interface Module works by receiving low-power control signals and converting them into relay switching actions:
- Control signal activates internal switching circuitry
- Relay contacts open or close depending on logic input
- Electrical isolation is maintained between control and load circuits
- External devices (valves, alarms, actuators) are safely controlled
This ensures protection of sensitive control electronics while enabling reliable switching of industrial loads.
