1-Channel Relay Module 5V with Optocoupler Low Level Trigger for Arduino AVR PIC

Description:

• this module conform international safety standard, the isolation groove between control areas and load area;
• with optical coupling isolation, triggering more reliable, more stable;
• the double FR-4 circuit board design;
• have power and relay operation instructions.The LED will be lit when relay on;
• signal input with a high level signal, the common pin;
• relay can directly control all kinds of equipment and load;
• one normally open pin and a normally closed pin;
• blue KF301 terminal, more convenient;
• module size: 53x18x18.5mm;

Module interface:

Input part:

• VCC:connect to power positive (according to the relay voltage range)
• GND: connect to power negative
• IN: relay module trigger pin (high level trigger)

Output part:

• Normally Opened (NO) : normally open pin of relay. NO pin is not connect to COM pin when relay off.NO pin is connect to COM pin when relay on;
• Common pin (COM) : Common pin of the relay;
• Normally closed (NC) : normally close pin of relay.NC pin is connect to COM pin when relay off.NC pin is not connect to COM pin when relay on;
