53255

    The 53255 is a DC solid state relay (SSR) designed for high  reliability commercial applications. This light weight device is resistant to damage from severe shock and vibration, and is immune to contact related problems inherent in ele-ctro-mechanical relays. The SSR of 53255 is enclosed in  a hermetic metal package to ensure reliability in harsh environments. Effective isolation of 1000 VDC between control and load circuits is achieved through the use of optical coupling.

    Functionally, the 53255 operates as a single-pole single-throw, normally open (1 Form A) DC solid-state relay. The SSR is actuated by an input current of 5 to 15 mA, which can be supplied from standard logic types such as open- collector TTL. Output of 53255 is provided by a power MOSFET capable of carrying a continuous current of 10 amperes.
