Overview
Reviews

This 4-relay module consists of four LEDs, four resistors, four NPN transistors, four diodes and four relays capable of handling up to 5A 50V AC.

The relays are large in size, yet compactly sized to allow for continuous operation even under adverse operating conditions. With the help of an additional transistor, the module can be quickly and easily switched with various low-current microcontrollers.

The optocouplers and diodes protect your controller from damage. The source of the power supply can be configured with a jumper located on the board.
