Product Details
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. Each way module can be set 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 ) , 4 relay status indicator ( red )
7. Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient
8. Module size : 73mm * 50mm * 18.5mm ( L * W * H )
9. Has four mounting bolts holes , hole 3.1mm, 67mm * 44.5mm 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-IN4: each way based on the settings , can be high or low to control the corresponding relay
Outputs :
a 12- line interface, the interface can be directly connected to all leads , user-friendly
1. NO1 - NO4: normally open relay interfaces , relay before the vacant after the pull shorted with COM
2. COM1 - COM4 Common Interface Relays
3. NC1 - NC4: normally closed relay interface relay shorted with COM ago , after the pull- vacant
High and low trigger selection :
1.S1-S4 in order to relay a way -4 road high and low trigger selection ;
2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger
Package Included:
1x 12V 4 Channel Relay Module With Optocoupler High and Low Level Trigger
