Electronics-Salon 8 Channel DPDT Signal Relay Module Board Operating Voltage DC 12V

8 Channel DPDT Signal Relay Module Board, DC 12V Version. RY12W-K high quality signal relays, LED indicator for each relay channel. Darlington transistors circuit driving relay, improve the reliability of action. Pitch 3.81mm / 0.15" screw terminal block, wire range 26-16AWG, strip length 5mm / 0.2", Metric M2 slotted screw. FR-4 fiber glass PCB, dual copper layers. Dimensions: 72.5mm x 150mm ( L x W ). Operating Voltage: DC 12V. Input control signal voltage: 0V - 0.5Vdc, low level, relay not action. 2.5V - 24Vdc, high level, relay action. Input control signal high level current: 2.5V: 0.1mA. 5V: 0.35mA. 12V: 1.1mA. 20V: 1.9mA Relay Spec: Relay Part Number: RY12W-K series. Contact Material: Gold Overlay Silver-Palladium. Contact Rating: 120VAC / 0.5A, 24VDC / 1A. Wire connection and PCB size: VCC: Power supply input. GND: Power supply ground and control signal ground. IN-X: Control signal input, Low: relay not action, High: relay action. COM / NO / NC: 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.
