2PCS 5V 8 Channel Relay Module With OPTO-Isolated High And Low Level Trigger Equipped with high-current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; Trigger current of opto-isolator: 5mA. The relay module Operating voltage 5V; Each channel of the module can be set by jumper cap high or low level trigger; It is 8 Channel Isolated 5V 10A Relay Module, each relay can individually switch on/off by an opto-isolated digital input, Standard interface can be directly connected with microcontrollers and be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, DSP, etc., very convenient.

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 voltage is 12V;

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 ) , 8 relay status indicator ( red )

7 . Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient

8 . Module size : 141.5mm * 50mm * 18.5mm ( L * W * H )

9 . Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm

Module Interface :

1. DC +: 12V positive power supply

2. DC-: negative power connection

3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relay

Relay outputs :24 line interface, the interface can be directly connected to all leads , user-friendly

1. NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM

2. COM1 - COM8: Relay Common Interface

3. NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacant

High and low trigger selection :

1.S1-S8 in order to relay a road -8 way 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:

2PCS*5V 8 Channel Relay Module With Optocoupler
