2 relay module with opto isolation, support for high and low level trigger 5V9V12V24V

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 * 41mm * 18.5mm ( L * W * H )
9 , with 4 fixing bolt holes , hole 3.1mm, 44.5mm * 35.5mm pitch

Module interface :
1, DC: positive power supply ( voltage at relay requirements, 5V.9V.12V and 24V options )
2, DC-: negative one
3, IN1: 1 channel signal trigger terminal can be set high or low level control relay
3, IN2: 2 -channel signal trigger terminal can be set high or low level control relay
Relay outputs :
1, NO1: 1 relay normally open interfaces , the relay becomes vacant before , pull shorting after the COM1
2, COM1: 1 relay common interface
3, NC1: 1 normally closed relay interface relay shorted before and COM1 , pull vacant post
4, NO2: 2 way normally open relay interface relay becomes vacant before , after and COM2 pull shorting
5, COM2: 2 Common Interface Relay
6, NC2: 2 way normally closed relay interface relay shorted before and COM2 , pull vacant post

High and low end of the trigger options :

1.S1 relay is a high and low trigger selection ;

2.S2 high and low for the two -way relay trigger selection ;

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