Description The Songle Single-channel 5V 30A Relay Module power failure relay is a 1-channel relay module board with LED indicators, It can be controlled by microcontrollers such as Arduino, AVR, PIC, ARM any other microcontroller operating at 5V. The relay module uses an authentic quality mechanical relay and the industry’s top quality subminiature two-way isolation optical coupling which gives you the strong anti-interference ability, and stable performance. The user can choose the relay control level, can be a high level off, also can be low level and off. The Songle Single-channel 5V 30A Relay Module Power Failure Relay contains a limited flow resistance, can directly use the power supply is negative control, you can also use the MCU I/O control. The relay module equips a power indicator light (red), 1 road relay status indicator light (blue). With this relay, you can easily control electrical appliances, lights, etc. Fault-tolerant design, even if the control line is brokes, the relay will not move. 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
