DIN Rail mount 8 Channel 10Amp SPDT Power Relay Module, DC 12V Version.
JS1-12V-F Power Relays. LED indicator for each relay channel. Darlington transistors circuit driving relay, improve the reliability of action.
DIN rail mount carrier: High quality Taiwan DINKLE fireproof nylon material DIN rail mount carrier (not China low quality carrier), can support width 35mm / 32mm / 15mm rail. FR-4 fiber glass dual layers PCB.
High quality terminal block: Pitch 5.0mm/0.197", Wire range 28AWG ~ 12AWG / 2.5mm square, Strip length 7mm. Screws - M2.5,steel,Cr3+ Zn plated. Pin header and Cage - Brass.
External dimensions: 152 x 87 x 43mm(L x W x H).

Operating Voltage / Current: DC 12V / 400mA.
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 Specification:
Part number: JS1-12V-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.
