5V 1Channel Relay Module With Optocoupler

Standard, isolation zone between control zone and load zone;
Optocoupler isolation, trigger more reliable and more stable; dual FR-4 circuit board design;
Power and relay operating instructions. LED lights when the relay is bright;
Signal input is high signal, the public pin relay can directly control a variety of devices and loads;
A normally open pin and a normally closed pin;
Blue KF301 terminal, more convenient;
Module Size: 53x18x18.5mm;

Module Interface:
Input section:
VCC: Connect the positive power supply (according to the relay voltage range)
GND: Connect to the negative power supply
IN: Relay Module Trigger Pin (High-level Trigger)
Output section:
NO (NO): Relay normally open pin. When the relay is disconnected, the NO pin is not connected to the COM pin; when the relay is ON, the NO pin is connected to the COM pin;
Common pin (COM): Relay common pin;
Normally closed (normally closed): normally closed relay pin, NC relay is disconnected, the NC pin connected to the COM pin, the relay connected to the NC pin is not connected to the COM pin;
