  9. 9. 25 Series PC Board Relays 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 resistor as a optional solution. This protection circuit can be used when the load impedance is smaller than the RC impedance in an AC load power circuit. R: Resistor of approximately the same resistance value as the load C: 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 load C: 0.1 to 1 µF This protection circuit can be used for DC load power circuits. Use a diode with the following ratings. Reverse withstand voltage: Power voltage of the load circuit x 10 Forward current: More than the load current. Prevents This protection circuit is very effective in arc suppression when opening the contact however, the capacitor is charged while the contacts are opened else the capacitor is discharged through the contacts, increasing the possibility of contact welding. This protection circuit is very effective in arc suppression when opening the contact however, a current flows to charge the capacitor, causing contact welding when the contacts are closed. Safety Precautions 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 and maintenance 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 neighboring poles 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 preferred time to complete soldering is within 4 seconds approximately.25/6 25 Series PC Board Relays
