Module Features:

1, The control signal voltage range:The trigger signal is low0-2V;High voltage should not exceed5V.

2Using isolation optocoupler, anti-interference ability, stable performance; trigger current only3mA.

3,1-16All on the road can be arbitrary/Closed, or any road.

4,Output format: direct contactAC 220V 10AorDC30V 10ALoad.

5Each relay common terminalCOMAre independent, user-friendly access to different signals, with each relay are normally closed and normally open port.

6, Each relay is equipped with an operation indicator, it pulls off, disconnect off.

7, User-friendly interface design, all interfaces can be a direct connection through the terminal leads, convenient.

8,Features4A fixing bolt hole, easy installation.

9,PCBBoard size:180MM (L) * 80MM (W) * 20MM (H).

Electrical parameters:
Supply voltage: 5V or 12V (DC)

Current supply: greater than200mA
Each relay can load:250V 10A (AC) or30V 10A (DC)

Product description:
1.To meet the use of the power supply, DC12V;
2.Power requirements wiring diagram, not reverse; 
3.ProductsLM2596SBuck chip slight fever, is a normal phenomenon, relay work long hours have normal heating phenomenon, are normal;
4.Load power relay to give the load to leave a margin, should avoid high-power (2000WLeft and right) and long hours of work environment, will have some impact on the life of the product.
