Whadda 2-channel solid state relay module

The WHADDA module from Whadda's two-channel fixed relay (SSR) can be used to quickly and efficiently switch AC on and off points without the use of moving parts (e.g., like a classic electromechanical relay). The SSR module utilizes a phototriac to provide galvanic isolation between the logic level and the AC load side. Both channels can be activated with a low logic level signal (0 - 1.5 V) by supplying a high logic level signal (3 - 5 V) to its corresponding channel signal input. Please note that this module can only switch AC currents up to a maximum of 2 A with a maximum voltage of 240 V AC. Attempting to use this module to switch DC loads or exceed the specified limits may damage the module and/or your connected devices.
