12V 2 Channel Relay Module With Optocoupler High Low Level Trigger

Paage included:
1 x 12V 2 channel relay driver module for arduino

Features:
Descrtion:
1. The module uses quality relay , normally open inteaces imum load : AC 250V/10A, 30V/10A
2. Using SMD OPTOCOUPLER isolation , driving ability , stable peormance ; 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. Inteace design humane, all inteaces can be connected directly via terminal wiring leads , very convenient
8. Module size : 50mm * 40mm * 16mm ( L * W * H )
9. Has four mounting bolts holes , hole 3.1mm

Inteace :
1. +: positive power suly ( voltage required by the relay , there 5V.9V.12V and 24V choice )
2. -: 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 inteaces , relay before floating, shorted pull with COM1
2. COM1: 1 relay common inteace
3. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
4. NO2: 2 -way normally open relay inteace, the relay before floating , pull ba and COM2 short
5. COM2: 2 Common Inteace relay
6. NC2: 2 -way normally closed relay inteace 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

High and low trigger selection :
1.Short jumper with LOW triggered when connected
2 When the jumper is high with high short trigger
