This is the 60V variant of the Fotek 5-60V SSR-50DD Solid State Relay in Relays, Solid State Relays. Available at ₹630.12 (₹534.00 + GST) with free shipping across India.
The DC To DC SSR-50DD Solid State Relay Module (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts. The types of SSR are photo-coupled SSR, transformer-coupled SSR, and hybrid SSR. A photo-coupled SSR is controlled by a low-voltage signal which is isolated optically from the load.
The control signal in a photo-coupled SSR typically energizes an LED which activates a photo-sensitive diode. The diode turns on a back-to-back thyristor, silicon-controlled rectifier, or MOSFET transistor to switch the load.
