Schneider Electric Solid State Relay, Single Phase, SPNO Contact Configuration - Zelio Series - SSP1D440BDT

Control the flow of current to your machinery using this solid state relay from Schneider Electric. It lets you carefully monitor the status of a circuit as it has both a visual indicator and an alarm to alert you of unexpected changes in the output. The unit comes with a thermal pad to aid the conduction of heat energy away from your equipment and prevent interference with nearby components.

Features & Benefits

• Test button for troubleshooting and debugging

• Rated load voltage of 1 to 150V DC with DC switching for versatility

• Maximum turn-on time of 0.1ms for highly responsive switching

• Panel mounting type and telescopic screw terminals support simple connection to your system

Applications

• Industrial computers

• Medical and scientific research

• Heating control applications

What are solid state relays?

Solid state relays are switches that use a semiconductor mechanism. These can either turn off or amplify a much larger current. With no moving parts, this type of relay tends to be quieter and deliver a longer operational life than electromechanical alternatives.
