Photorelays

Toshiba Photorelays are ideal for security systems, mechanical relay replacements, factory automation, and measuring instruments. General-purpose, high-capacity, and lower CR photorelays are semiconductor relays made up of an LED optically coupled to a MOSFET, used mainly as signal relay replacements. These Toshiba photorelays are available in various packages with an operating temperature range of -20°C to +110°C.
