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.

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. Use a non-corrosive rosin flux. 800-262-IDEC (4332) • USA & Canada 817 Varistor Diode RC Varistor Operating Instructions Relays & Sockets Operating Instructions con’t Other Precautions 2. UL and CSA ratings may differ from product rated values determined by IDEC. 1. General notice: To maintain the initial characteristics, do not drop or shock the relay. 3. Do not use relays in the vicinity of strong magnetic field, as this may affect relay operation. The relay cover cannot be removed from the base during normal operation. To maintain the initial characteristics, do not remove the relay cover. Use the relay in environments free from condensation, dust, sulfur dioxide (SO ), and hydrogen sulfide (H S). 2 2 Make sure that the coil voltage does not exceed applicable coil voltage range.
