Product overview The Whadda 4-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.
