Relay modules

Relay modules play a special role in mechanics, automation and electronics. The precision and reliability of the small and inconspicuous elements results in stable operation of the entire system. The efficient relay module provides microcontroller control and extensive customisation options. They conveniently separate the power circuit from the control circuit. Solectroshop offers a particularly extensive range of these types of devices. Check our offer at Solectroshop
