DESCRIPTION
The 53012 is a military SPST solid-state relay. This light-weight device is resistant to damage from shock and vibration, and
is immune to contact-related problems (contamination, arcing) associated with mechanical equivalents.
Optical coupling between the input and output stages provides effective isolation up to 1000 volts AC RMS. Power FET
outputs eliminate bipolar offset, and minimize output voltage drop.
The control logic is TTL compatible, and will accommodate bias supplies between 3.8 and 32 VDC.
Integral short-circuit protection is provided in the 53012. This unit senses excessive current flow while under load or while
switching, and respond by opening the output. The output will remain blocked indefinitely until the short is removed, and the
unit reset. This feature prevents damage to the unit, and also averts further system failures that may be caused by the short-
circuit. Resetting the unit can be accomplished by cycling the input control.
This solid-state relay is ideal for use in military systems, or wherever high reliability, low power actuation, and light weight are
design considerations. Applications include general purpose signal switching and electronic load control.
