The 1 Channel 12V 30A Relay Module Power Failure Relay is a versatile 1-channel relay module board with LED indicators. It can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM, or any other microcontroller operating at 12V. The relay module features an authentic quality mechanical relay and top-quality subminiature two-way isolation optical coupling, providing strong anti-interference ability and stable performance.
The user can choose the relay control level, whether it be a high level off or low level and off. The module contains limited flow resistance, allowing direct use of the power supply for negative control or MCU I/O control. Equipped with a power indicator light (red) and a relay status indicator light (blue), this relay module makes it easy to control electrical appliances and lights.
Even in the event of a control line break, the relay will not move, thanks to its fault-tolerant design.
Module Interface:
- DC+: DC power supply positive pole
- DC-: DC power supply negative pole
- IN: Signal triggering pin
- JD+: Relay control voltage positive
- JD-: Relay control voltage negative
With the high and low-level trigger mode selection, the 1 Channel 12V 30A Relay Module Power Failure Relay offers flexibility in usage. By connecting the appropriate jumpers and pins, users can easily set the trigger level according to their requirements.
