This is a very simple module board, no paper specifications, any questions, feel free to tell me.

Wire connection and PCB size:

VCC: Power supply input, 48V DC.

GND: Power supply ground and control signal ground.

INx: Control signal input, Low: relay OFF, High: relay ON.

COM / NO / NC: (C1=COM1, C2=COM2)

Control signal state low, the relay OFF, COM - NO disconnected, COM - NC connected.

Control signal stage high, the relay ON, COM - NO connected, COM - NC disconnected.
