Features:
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 voltage is 5V, 9,12 V, 24V are available ;
4.The module can be set to high or low triggered by jumper
5.Fault-tolerant design , even if the control line is broken , the relay will not operate ;
6.The power indicator ( green ) , relay status indicator ( red )
7.Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8.Module size : 50mm * 41mm * 18.5mm ( L * W * H )
9.Has four mounting bolts holes , hole 3.1mm, 44.5mm * 35.5mm pitch

Interface:
1. DC +: positive power supply ( voltage required by the relay , there 5V.9V.12V and 24V choice )
2. DC-: negative power connection
3. IN1: 1 channel signal to trigger the end , you can set a high or low level control relay
3. IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Outputs:
1. NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1
2. COM1: 1 relay common interface
3. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
4. NO2: 2 -way normally open relay interface, the relay before floating , pull back and COM2 short
5. COM2: 2 Common Interface relay
6. NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post

High and low trigger selection:
1.S1 as a relay trigger selection of high and low ;
2.S2 high and low for the two -way relay trigger selection
3.Com with low short circuit, triggering the corresponding relay is low , while the high end of the short com high trigger

Package Included:
1*5V 2 Channel Relay Module
