    Product Description

    Description:

    • Normally open interface maximum load: AC 250V/10A, DC 30V/10A.
    • SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA.
    • Fault-tolerant design, the relay will not move even if the control line is broken.
    • Power indicator (green), relay status indicator (red).
    • The interface is designed humanized, and all the interfaces can be directly connected by wiring terminals, which is very convenient.

    Two module interface:

    1. DC+: Connect the power supply positive pole (voltage 3.3V).
    2. DC-: Connect the power negative pole.
    3. IN: Low level (3.3V) control relay pull in.

    Relay output terminal:

    1. NO: Relay normal open, the relay suspends before pulling in, then short-connect with the COM.
    2. COM: Relay common interface
    3. NC: Relay normal close, short connected with COM before pulling in, then suspended after pulling in.

    Package Included:

    Relay Module x (# purchased)
