Solid State Relay Module 5v 4-Channel High Level Trigger

This module is ideally suited to controlling larger voltages with project. This is a 4 channel relay module which can be used to activate up to 240V AC. This allows you to build in device control, operating lighting or triggering systems when the module is triggered.

With the labeled screw terminals it's easy to connect.
