5V: 0.35mA.
12V: 1.1mA.
20V: 1.9mA.

Relay Specification:
Part number: JS1-24V-F power relays.
Contact Rating: 125VAC/250VAC 10Amp or 30VDC 5Amp.

Wire connection:
VCC: Power supply input.
GND: Power supply ground and control signal ground.
CH-x: Control signal input, Low: relay OFF, High: relay ON.
COM / NO / NC: (Cx=COMx) .
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.

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