Solid State Relays

We offer Solid State Relay, which is available in different forms such as photo-coupled SSR, transformer-coupled SSR and hybrid SSR. These solid state relays are electronic devices that contain no moving part. Our photo-coupled SSR is controlled by a low voltage signal, which is isolated optically from the load. Due to the control signal of photo coupled SSR, a LED appears that activates a photo-sensitive diode, which turns on a back-to-back thyristor, silicon controlled rectifier, or MOSFET transistor to switch the load.
