Electronics-Salon 8 Channel 10Amp SPDT Power Relay Module Board Operating Voltage DC 24V

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. Datasheet: https://images-na.ssl-images-amazon.com/images/I/91AHtk3PT3L.pdf
