1 road with a coupler relay module, support for high-level triggered 5V/9V/12V/24V

 module description :

1, the module uses genuine quality relay , normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A;
2 , using SMD optocoupler isolation , driving ability , stable performance ; trigger current 5mA;
3 , the module Operating voltage 5V, 9,12 V, 24V are available ;
4, the module can be high or low by a jumper setting trigger ;
5 , fault-tolerant design , even if the control line is broken , the relay will not operate ;
6 , the power indicator ( green ) , the relay status indicator ( red )
7 , the interface design of human nature , all interfaces are available through a direct connection terminal leads , very convenient
8 , module size : 50mm * 26mm * 18.5mm ( L * W * H )
9 , with 4 fixing bolt holes , hole 3.1mm, 44.5mm * 20.5mm pitch

 module interface :

1, DC +: positive power supply ( voltage at relay requirements, 5V.9V.12V and 24V options )
2, DC-: negative one
3, IN: can be high or low level control relay

Relay outputs :
1, NO: normally open relay interface, the relay becomes vacant before , pull short after the COM
2, COM: Common Interface Relays
3, NC: normally closed relay interface relay shorted to COM before , pull vacant post

High and low end of the trigger options :

1 shorting jumper with LOW is low when the trigger ;

2 short jumper with high high when triggered.
