• Max. Load Current: 2 A
• Supply Voltage: 5 V DC

The Velleman 4 Channel Solid State Relay Module uses a photometric to provide galvanic isolation between the logic level side and the AC load side. All four of the channels can be switched on by providing a HIGH logic level signal (3 - 5 V), and off by providing a LOW logic level signal (0 - 1.5 V) to its corresponding channel signal input.

The Whadda four-channel Solid State Relay (SSR) module can be used to quickly and efficiently switch AC loads on and off without using any moving parts (e.g. a classic electromechanical relay).
