5V/9V/12V/24V 2 Channel Relay Module With Optocoupler High Low Level Triggered 2-way Relay Module for Arduino

Note:The default delivery is 5V, need 9V/12V/24V, please leave a message!!!

• The module adopts genuine quality relay, normally open interface, maximum load: AC 250V/10A, DC 30V/10A;

• It adopts SMD optocoupler isolation, with strong driving ability and stable performance. The trigger current is 5mA;

• Module operating voltage is 5V, 9, 12V and 24V to choose from;

• Modules can be triggered by jumper, high or low level;

• Fault tolerant design, even if the control line is broken, the relay will not act;

• Power indicator (green), relay status indicator (red)

• The interface design is user-friendly, and all interfaces can be directly connected through the wiring terminals, which is very convenient

• Module size: 50mm * 41mm* 18.5mm

• With 4 fixed bolt holes, hole 3.1mm, spacing 44.5mm*35.5mm

Technical parameter:

Module interface:

• DC+: connect the power positive (voltage, as required by the relay, with 5V.9V.12V and 24V options)

• DC-: the negative pole of the power supply

• IN1:1 circuit signal trigger terminal, can set high or low level control relay attract

• IN2:2 circuit signal trigger terminal, can set high or low level control relay attract

Relay output:

• NO1:1 road relay normally open interface, the relay before hanging, suspended, and after the short connection with the COM1

• COM1:1 road relay common interface

• NC1:1 road relay normally closed interface, before the relay is pulled in, short connection with COM1, left after attracting

• NO2:2 road relay normally open interface, the relay before hanging, suspended, and after the short connection with the COM2

• COM2:2 road relay common interface

• NC2:2 road relay normally closed interface, before the relay is pulled in, short connection with COM2, left after attracting.

High level trigger select end:

• S1 for 1 way relay, high and low level trigger selection;

• S2 for 2 way relay, high and low level trigger selection;

• When the com is shorted to the low, the corresponding relay is triggered at a low level, and the high is shorted to the high level when the com is short circuited
