Safety Precautions **Turn off the power to the RJ relay prior to installation, removal, wiring, maintenance, and inspection. Failure to turn power off may cause electrical shock or fire. **Observe the specifications and rated values, otherwise electrical shock or fire may occur. **Use wires of the proper size to meet the voltage and current requirements. **Tighten terminal screws to a proper tightening torque. 7 RJ Series Slim Power Relay Plug-in Terminal (Bifurcated Contacts) Instructions 1. Driving Circuit for Relays When driving an element at the same time as the relay is operating, special consideration is needed when designing the circuit. As shown in the incorrect circuit example above, leakage current (Io) flows through the relay coil while the relay is off. Leakage current causes coil release failure or adversely affects the vibration and shock resistance. Design a circuit as shown in the correct example. 5. Surge suppression for transistor driving circuits: When the relay coil is turned off, a high-voltage pulse is generated. Be sure to connect a diode to suppress the counter electromotive force. Then, the coil release time becomes slightly longer. To shorten the coil release time, connect a Zener diode between the collector and emitter of the controlling transistor. Select a Zener diode with a Zener voltage slightly higher than the power voltage. 1. To make sure of correct relay operation, apply rated voltage to the relay coil. 2. Input voltage for DC coil: Complete DC voltage is best for stable operation of the coil power. When using a power supply containing a ripple voltage, suppress the ripple factor within 5%. When power is supplied through a rectification circuit, relay operating characteristics, such as pickup voltage and dropout voltage, depend on the ripple factor. Connect a smoothing capacitor for better operating characteristics as shown below. Smoothing Capacitor + - R Relay Counter emf suppressing diode + Pulsation 2. Protection for Relay Contacts 1. The contact ratings show maximum values. Make sure that these values are not exceeded. When an inrush current flows through the load, the contact may become welded. If this is the case, connect a contact protection circuit, such as a current limiting resistor. 2. Contact protection circuit: When switching an inductive load, arcing causes carbides to form on the contacts, resulting in increased contact resistance. In consideration of contact reliability, contact life, and noise suppression, use of a surge absorbing circuit is recommended. Note that the release time of the load becomes slightly longer. Check the operation using an actual load. Incorrect use of a contact protection circuit will adversely affect switching characteristics. Four typical examples of contact protection circuits are shown in the following table: Emax = Maximum of pulsating current Emin = Minimum of pulsating current Emean = DC mean value 3. Operating the relay in sync with an AC load: If the relay operates in sync with the AC power voltage of the load, the relay life may be reduced. If this is the case, select a relay with the required load reliability. Or, make the relay turn on and off irrespective of the AC power phase or near the point where the AC phase crosses zero voltage. TE Load EAC Vin EAC Power C R Ind. Load RC Vin 4. Leakage current while relay is off: Incorrect Power TE R lo C Ind. Load R Diode + Power Ind. Load D - Power Varistor R Varistor Correct Load C Power This protection circuit is very effective in arc suppression when opening the contacts. But, when the contacts are Load closed, a current flows to charge the capacitor, causing contact welding. 3. Notes on PC Board Mounting Emax - Emin x 100% Emean R C Power This protection circuit is very effective in arc suppression when opening the contacts. But, the capacitor is charged while the contacts are opened. When the contacts are closed, the capacitor is discharged through the contacts, increasing the possibility of contact welding. Generally, switching a DC inductive load is more difficult than switching a DC resistive load. Using an appropriate arc suppressor will improve the switching characteristics of a DC inductive load. R Relay DC Emin Emax Emean Ripple Factor (%) - 3. Do not use a contact protection circuit as shown below: Ind. Load 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 F 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 F 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 This protection circuit can be used for both AC and DC load power circuits. For a best result, when using on a power voltage of 24 to 48V AC/DC, connect a varistor across the load. When using on a power voltage of 100 to 240V AC/DC, connect a varistor across the contacts. * When mounting 2 or more relays on a PC board, keep a minimum spacing of 5mm in each direction. * Manual soldering: Solder the terminals at 350C within 3 sec. Using a soldering iron of 60W (Sn-Ag-Cu type) is recommended. * Auto-soldering: Solder at 250C within 4 to 5 sec. * Because the terminal is filled with epoxy resin, do not excessively solder or bend the terminal. Otherwise, air tightness will degrade. * Avoid touching the relay cover or the epoxy filled terminal with the soldering iron. * Use a non-corrosive resin flux. 4. Others 1. General notice: * To maintain the initial characteristics, do not drop or shock the relay. * 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 dust, sulfur dioxide (SO2), hydrogen sulfide (H2S), or organic gases. * Make sure that the coil voltage does not exceed the applicable coil voltage range. 2. Connecting outputs to electronic circuits: When the output is connected to a load which responds very quickly, such as an electronic circuit, contact bouncing causes incorrect operation of the load. Take the following measures into consideration. a. Connect an integration circuit. b. Suppress the pulse voltage due to bouncing within the noise margin of the load. 3. Do not use relays in the vicinity of strong magnetic fields, as this may affect relay operation.
