8 Channel 10Amp SPDT Power Relay Module Board.

This item has been assembled, and electrical test passed.
JS1-24V-F Power Relays.
LED indicator for each relay channel.
Darlington transistors circuit driving relay, improve the reliability of action.
FR-4 Fiber glass PCB (Double Layer).

Operating Voltage/Current(max.): DC24V / 280mA (relay all action).
Input control signal voltage:
0V - 0.5V Low state (relay not-action),
2.5V - 20V High state (relay action).
Input control signal high state current:
2.5V: 0.1mA.
5V: 0.35mA.
12V: 1.1mA.
24V: 2.4mA.

Relay Spec:
Part Number: JS1-24V-F Power Relays.
Contact Rating: 125VAC/250VAC 10Amp or 30VDC 5Amp.

Wire connection and PCB size:
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.
