Product Description

Using this relay board allows you to trigger relays with high and low levels, and control them remotely with any 5V digital input of your

Typical parameter details are maximum load of normally open interface AC 250 volts @ 10 amps, DC 30 volts @ 10 amps, trigger current 5 mA The 5v relay control board uses SMD optocoupler isolation for strong driving ability and stable operation.

A fault-tolerant design means the relay module will not operate even if the control line is disconnected all interfaces are via directly connected terminals and due to the humanized interfaces, it is very convenient to use.

Highly compatible the relay module can directly be controlled by 5V logic signals provided by the microcontroller, which means it can be used with 8051, Raspberry Pi, PIC, DSP, ARM, AVR, MSP430, and TTL logic, among others.

This 5V relay board can be connected with various devices including Raspberry Pi, CNC machines, ARM boards, PIC designs, AVRs, MCUs, PS4 and more.
