5V 4 Channel Relay Module With OPTO-Isolated High and Low Level Trigger

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 has a 5V working voltage options ;

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 has 24V option)

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 :

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
