Description
The CT-501 is a single pole DC solid-state relay
featuring current limiting and thermal shutdown. The
input is a single LED, typical control current is 20 mA.
The main intended application is in 28V aircraft
systems. When used in this application the relay can
withstand a direct short on the output. The thermal
shutdown will then keep the output in the off state until
the temperature drops. The output will then attempt to
turn back on. There is no need to re-cycle the input.
The relay is packaged in a 6 pin hermetic package,
with a 4 pin half size crystal can package as an option.
Additional options of ON resistance and output voltage
are also available as well as commercial grade relays.
Please consult our sales department for further
information regarding specific requirements.
Full custom solid-state relay design services are also
available.
