Contact protection circuit: circuit, the relay operating characteristics, such as pickup voltage and dropout When switching an inductive load, arcing causes carbides to form on the voltage, depend on the ripple factor. Connect a smoothing capacitor for better contacts, resulting in increased contact resistance.

Note that the release time of the load becomes slightly Pulsation longer. Check the operation using the actual load.

Generally, switching a DC inductive load is more difficult than switching a DC resistive load. Using an appropriate arc suppressor, however, will improve the switching characteristics of a DC inductive load. Soldering 1. When soldering the relay terminals, use a soldering iron of 30 to 60W, and quickly complete soldering (within approximately 3 seconds). 2.
