1-way Electromagnetic Relay Module Optocoupler Isolation Low Level Trigger PLC Control Driver Board 3V5V12V24V

Product Introduction:
Module adopts high quality relay, normally open interface larger load
Ac 250V/10A, straight 30;
Adopts patch optocoupler isolation, strong driving ability, stable performance; Trigger current 5MA;
Fault tolerant design, even if the control line is broken, the relay will not operate;
Power indicator (green), Relay status indicator (red)
Interface design humanized, all interfaces can be directly connected through the wiring terminals, easy to use.
Module interface
1, VCC: connected to the positive electrode of the power supply (3.3V)
2. GND: Connects to the negative terminal of the power supply
3, IN: low level control relay suction
Relay output:
1, NO: the relay is normally open interface, the relay is suspended before suction, and the COM is shorted after suction
2, COM: relay public interface
3, NC: relay normally closed interface, relay short with COM before closing, suspended after closing
