    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, and then short-connect with the COM.
    2. COM: Relay common interface
    3. NC: Relay normal close, short connected with COM before pulling inand suspended after pulling in.
    Package Included:

    1 x 1 Channel 3.3V Relay Module

    Questions & Answers(5)
    Q: This doesn't come with any schematics. On the input side there are markings for VCC, In and GND but there's no indication as to whether a high level or low level turns the relay on. It's worse on the output side. There, there are just three cryptic markings which I am unable to decipher. The minimal written documentation on the site doesn't clarify things.
