8 relay module with opto isolation, high and low trigger 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 , each channel module jumper settings are available through the high or low trigger ;
5 , fault-tolerant design , even if the control line is broken , the relay will not operate ;
6 , the power indicator ( green ) , 8 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 : 141.5mm * 50mm * 18.5mm ( L * W * H )
9 , with 4 fixing bolt holes , hole 3.1mm, pitch 136mm * 44.5mm

module interface :
1, DC +: positive power supply ( voltage at relay requirements, 5V.9V.12V and 24V options )
2, DC-: negative one
3, IN1-IN8: according to the settings for each channel , can control the corresponding high or low relay
Relay outputs : There are 24 line interface, all interfaces can be connected directly leads, user-friendly
1, NO1 - NO8: normally open relay interface, the relay becomes vacant before , pull short after the COM
2, COM1 - COM8: Relay Common Interface
3, NC1 - NC8: normally closed relay interface relay shorted to COM before , pull vacant post

High and low end of the trigger options :

1.S1-S8 relay a road -8 were high and low trigger channel selection ;

2.com with low short-circuited , the corresponding relay is low trigger , com and high -side short-circuited when the trigger is high
