CT-501

0.2 Amp 70 Volt DC Solid State Relay

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 20mA.

The main intended application is in 28V Aircraft Systems. When used in this application the Relay can withstand a direct short 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.
