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. In consideration of contact operating characteristics as shown below. reliability, contact life, and noise suppression, use of a surge absorbing circuit is recommended. Note that the release time of the load becomes slightly Pulsation longer. Check the operation using the actual load. Incorrect use of a contact protection circuit will adversely affect switching characteristics. Four typical Smoothing Emin Emax Emean DC Capacitor examples of contact protection circuits are shown in the following table: + R Relay Emax – Emin – Ripple Factor (%) × 100% This protection circuit can be used when the load Emean Emax = Maximum of pulsating current impedance is smaller than the RC impedance in an Emin = Minimum of pulsating current AC load power circuit.

Do not use a contact protection circuit as shown below: between the collector and emitter of the transistor. Select a Zener diode with a Zener voltage slightly higher than the power voltage.

Generally, switching a DC inductive load is more diffi cult than switching a DC resistive load. Using an appropriate arc suppressor, however, will improve the switching characteristics of a DC inductive load. Soldering 1.
