A solid state relay (SSR) is an electronic switch that contains no moving parts. The SSR-100DA Relay Module uses a photo-coupled SSR type, where a low voltage signal energizes an LED to activate a photo-sensitive diode, which then turns on a back-to-back thyristor, silicon controlled rectifier, or MOSFET transistor to switch the load.

Do not exceed the specified voltage and current ratings.
Use ring or fork connectors with the four screw terminals for secure connections.
