5V Relay Module with Optocoupler Low Level Trigger Expansion Board for Arduino – 2 channels


These relays work great, genuine work horses, with SMD optocoupler isolation, and very stable performance.


It can be used as a microcontroller development board module, or as home appliance control.


Normally open interface and can be set to high or low triggered by jumper.


Maximum load: AC 250V/10A, DC 30V/10A.


Trigger current: 5mA


Fail safe design, even if the control line is broken, the relay will not operate.


Convenient terminal wiring leads, easy to connect and operate


5V relay module


TTL control signal of 5V-12V


 Controls DC or AC signal, and controls 110V or 220V AC load.


There is a normally open and a normally closed contact


With power indicator


The control pin has a pull-down circuit to prevent floating relay from malfunctioning




·       Optocoupler isolation, good anti-interference


·       Low level pull-in, high-level release. Pull, the status LED ON. Release, status LED OFF


·       VCC for the system power, JD_VCC for the relay power
