This protection circuit is very effective in arc suppression whenopening the contact however, the capacitor is charged while thecontacts are opened else the capacitor is discharged through thecontacts, increasing the possibility of contact welding.
This protection circuit is very effective in arc suppression whenopening the contact however, a current flows to charge the capacitor,causing contact welding when the contacts are closed.
Protection
When an inrush current flows through the load, the contact may become welded. The contact ratings show maximum values,Make sure that these values are not exceeded. Contact a contact protection circuit, such as a current limiting resistoras a optional solution.
This protection circuit can be used when the load impedance is smaller than theRC impedance in an AC load power circuit.R: Resistor of approximately the same resistance value as the loadC: 0.1 to 1 µF
This protection circuit can be used for both AC and DC load power circuits.R: Resistor of approximately the same resistance value as the loadC: 0.1 to 1 µF
This protection circuit can be used for DC load power circuits. Use a diode withthe following ratings.Reverse withstand voltage: Power voltage of the load circuit x 10Forward current: More than the load current.

Back emf suppressing diode
Apply rated voltage to the relay coil to ensure correct relay type.When using a power supply containing a ripple voltage, suppressthe ripple factor within 6% however, a complete DC voltage is best for the coilpower to make sure of stable relay operation.Pickup voltage and dropout voltage depend on the ripple factorwhen power is supplied through a rectificationcircuit. Include a smoothing capacitor for betteroperation.
Special consideration should be taken when driving an element at the same time as the relay operation for the circuit design. Leakage current (Io) flows through the relay coil while the relay is off. Leakage current causes coilrelease failure or adversely affects the vibration resistance and shock resistance. It is advisable to design a circuit as shown.
Connecting a diode to suppress at the back electromotive force prevents a high-voltage pulse which is generated when the relay coil is turned off, causing transistor to deteriorate or break, make sure the coil release time is slightly longer.To shorten the coil release time, connect a Zener diode which is slightly higherthan the power voltage, between the collector and emitter of the transistor.

Do not drop, shock or remove the relay cover to maintain the initial characteristics.The relay cover cannot be removed from the base during normal operation.Use the relay in environments free from dust, condensation, dioxide or hydrogen sulfide.
Make sure that the coil voltage does not exceed applicable coil voltage range.Prevent usage of relays in the vicinity of strong magnetic field, as that my cause in malfunctioning of relays.
Failure to turn off power before wiring, installation, removal andmaintenance may cause electrical shock or fire hazard.
Attention on specifications and rated values to prevent electrical shock or fire hazard.Use wires of the proper size to meet voltage and current requirements.
Tighten the terminal screws on the relay socket to the proper tightening torque.
Prevent using the check button as a switch.The durability of the check button is a minimum of 200 operations.It is advisable to apply a positive voltage to terminals of neighboring poles and a negative voltage to the other terminals of neighboringpoles when using DC loads on 4PDT relays to prevent the possibility of short circuits.
A soldering iron of 30 to 60W would be recommended when soldering the relay terminals and the preferredtime to complete soldering is within 4 seconds approximately.
