The WHADDA module of Whadda Dual Channel Solid Channel Relay (SSR) can be used to quickly and efficiently switch the switching and off and off points without using moving parts (such as a classic electromechanical relay).The SSR module uses a phototriac to provide galvanic isolation between the logical plane and the AC load side. Both channels can be switched on with a low logic level signal (0 - 1.5 V) by providing a high logic level signal (3 - 5 V) at its corresponding channel signal input.Note that this module can only switch alternating currents up to a maximum of 2 A with a maximum voltage of 240 V AC. If you try to use this module to change DC loads or exceed the specified limits, the module and / or your connected devices may be damaged!This text is machine translated.
