Description:
1 channel 5V 30A Relay Module Power Failure Relay
The Songle Single channel 5V 30A Relay Module Power Failure Relay is a board that has one relay and LED indicators. It can work with microcontrollers like Arduino, AVR, PIC, ARM and others that operate at 5V.
The relay module uses a high-quality mechanical relay and a subminiature two-way isolation optical coupler that are industry-leading. They provide strong resistance to interference and reliable performance.
The user can choose how to control the relay level. It can be either high or low level off. The Songle Single-channel 5V 30A Relay Module Power Failure Relay has a current-limiting resistor that allows direct use of the negative power supply for control. Alternatively, the user can use the MCU I/O for control.
The relay module has a power indicator light (red) and a relay status indicator light (blue). With this relay, the user can easily control electrical devices, lights and more.
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
Features
- Optical coupling isolation, driving ability is strong, stable performance; Trigger current is 5mA
- The module can be set high level or low-level trigger by the jumper
- Rated current of the interface is 16A
- DC+ and JD+ shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminal.
- High and low-level trigger mode selection. Jumper and L pin connection, IN pin, is low-level trigger Jumper and H pin connection, IN pin, is the high-level trigger.
