4 channel solid state relay module (wpm464)

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. like a classic electromechanical relay). The SSR module uses a phototriac to provide a 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. Note that this module can ONLY SWITCH AC CURRENTS, up to a maximum of 2 A, with a maximum voltage of 240 V AC. Trying to use this module to switch DC loads or exceeding the specified limits can damage the module and/or your connected devices!
