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. 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!
