    Description
    Product introduction:
    1. This module conform international safety standard, the isolation groove between control areas and load area
    2. With optical coupling isolation, triggering more reliable, more stable
    3. The double FR-4 circuit board design
    4. Have power and relay operation instructions.The LED will be lit when relay on
    5. Signal input with a high level signal, the common pin and the normally opened pin will connected
    6. Relay can directly control all kinds of equipment and load
    7. One normally open pin and a normally closed pin
    8. Blue KF301 terminal, more convenient
    9. Module Size: 53x18x18.5mm/2.08*0.7*0.72
    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
    • Onboard 12V, 10A/250VAC, 10A 30VDC relay
