DESCRIPTION

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 electro-mechanical relays. The SSR 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 device 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 is provided by a power MOSFET capable of carrying a continuous current of 10 amperes.
