Applications

Output expansion for safety relay modules and safety controllers Contacts of a force guided relay are forced to open and close by a guide connected to the armature. Due to requirements of standard EN50205, a force guided relay has independent NO and NC contacts. If a NO con- tact welds, a NC contact will not close even when the relay coil is turned off (de-energized) and must maintain a gap of at least 0.5 mm. Furthermore, if a NC contact welds, a NO contact will not close when the relay is turned on (ener- gized) and must maintain a gap of at least 0.5 mm. (General-purpose relays do not have the above characteristics.) What is a force guided relay? Relays used in safety circuits to detect failures such as contact welding and damage to the contact spring.

RF1V Force Guided Relays / SF1V Relay Sockets Instructions 1. Driving Circuit for Relays 1. To make sure of correct relay operation, apply rated voltage to the relay coil. Pickup and drop- out voltages may differ according to operating temperature and conditions. 2. Input voltage for DC coil: A complete DC voltage is best for the coil power to make sure of stable operation. When using a power supply containing a ripple voltage, sup- press the ripple factor within 5%. When power is supplied through a rectifications circuit, relay operating characteristics, such as pickup volt- age and dropout voltage, depend on the ripple factor. Connect a smoothing capacitor for better operating characteristics as shown below. – R Smoothing Capacitor Relay Pulsation Emin Emax Emean DC Ripple Factor (%) × 100%Emax – Emin Emax= Maximum of pulsating current Emin= Minimum of pulsating current Emean = DC mean value Emean 3. Operating the relay in sync with an AC load: If the relay operates in sync with AC power volt- age of the load, the relay life may be reduced. If this is the case, select a relay in consideration of the required reliability for the load. 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. R Vin EAC TE Load Vin EAC 4. Leakage current while relay is off: When driving an element at the same time as the relay operation, special consideration is needed for the circuit design. As shown in the incorrect circuit below, leakage current (Io) flows through the relay coil while the relay is off. Leakage current causes coil release failure or adversely affects the vibration resistance and shock resistance. Design a circuit as shown in the correct example. Incorrect R TE lo Correct R 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. R Counter emf suppressing diode Relay 6. The coil terminal of the relay has polarity. Connect terminals according to the internal connection diagram. Incorrect wiring may cause malfunction. 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 an 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: RC Power CR 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 μF C RPower Ind. Load 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 Diode DPower Ind. Load 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 × 10 Forward current: More than the load current Varistor Varistor Power Ind. Load 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. 3. Do not use a contact protection circuit as shown below: Power C Load 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. C Load Power This protection circuit is very effective in arc suppression when opening the contacts. But, when the contacts are closed, a current flows to charge the capacitor, causing 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. 3. Usage, transport, and storage conditions 1. Temperature, humidity, atmospheric pressure during usage, transport, and storage. ➀ Temperature: –45°C to +85°C (no freezing) When the temperature is 70 to 80°C, reduce the 6A max. switching current by 0.1 A/°C ➁ Humidity: 5 to 85%RH (no condensation) The humidity range varies with temperature. Use within the range indicated in the chart below. ➂ Atmospheric pressure: 86 to 106 kPa Operating temperature and humidity range Tolerance Range (Avoid freezing when using at temperatures below 0ºC) (Avoid condensation when using at temperatures above 0ºC) 0–40 85 Humidity (%RH) Temperature (ºC) 2. Condensation Condensation occurs when there is a sudden change in temperature under high temperature and high humidity conditions. The relay insula- tion may deteriorate due to condensation. 3. Freezing Condensation or other moisture may freeze on the relay when the temperatures is lower than 0ºC. This causes problems such as sticking of movable parts or delay in operation. 4. Low temperature, low humidity environments Plastic parts may become brittle when used in low temperature and low humidity environments. 4. Panel Mounting When mounting DIN rail mount sockets on a panel, take the following into consideration. Use M3.5 screws, spring washers, and hex nuts.• For mounting hole layout, see page 6.• Keep the tightening torque within 0.49 to 0.68 • N

• m. Excessive tightening may cause damage to the socket. 5. Others 1. General notice: ➀ To maintain the initial characteristics, do not drop or shock the relay. ➁ The relay cover cannot be removed from the base during normal operation. To maintain the initial characteristics, do not remove the relay cover. ➂ Use the relay in environments free from condensation, dust, sulfur dioxide (SO 2), and hydrogen sulfide (H2S). ➃ The RF1V relay cannot be washed as it is not a sealed type. Also make sure that flux does not leak to the PC board and enter the relay. 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 opera- tion of the load. Take the following measures into consideration. ➀ Connect an integration circuit. ➁ Suppress the pulse voltage due to bouncing within the noise margin of the load. 3. Do not use relays in the vicinity of strong mag- netic field, as this may affect relay operation. 4. UL and CSA ratings may differ from product rated values determined by IDEC. 6. Notes on PC Board Mounting When mounting 2 or more relays on a PC board, • keep a minimum spacing of 10 mm in each direction. If used without spacing of 10 mm, rated current and operating temperature differs. Consult IDEC. Manual soldering: Solder the terminals at 400°C• within 3 sec. Auto-soldering: Preliminary heating at 120°C • within 120 sec. Solder at 260°C±5°C within 6 sec. Because the terminal part is filled with epoxy • resin, do not excessively solder or bend the terminal. Otherwise, air tightness will degrade. Avoid the soldering iron from touching the relay • cover or the epoxy filled terminal part. Use a non-corrosive resin flux. (090319)

If a short-circuit failure occurs at either of the S1 channels, when the safety guard is opened, K2 does not turn off but K1 turns off, so safety function (power interruption to the motor) is maintained. The system does not restart because the NC contact of K2 remains open and K3 is not energized even when S2 is turned on. 2. If a short-circuit failure occurs between S1 channels, the potential dif- ference of K1 and K2 coils become 0V, turning K1 and K2 off. (Fault detection function between safety input circuits) 3. If NO contact of KM1 is welded, KM2 turns off when the safety guard is opened, so the safety function (power interruption to the motor) is maintained. The system does not restart because the NC contact remains open and K3 is not energized even when S2 is turned on. 4. If the NO contact of K1 is welded, K2 turns off when the safety guard is opened, so the safety function (power interruption to the motor) is maintained. The system does not restart because the NC contact of K1 remains open and K3 is not energized even when S2 is turned on. 5. If NC contact of K3 is welded, K1 and K2 turn off when the safety guard is opened, so the safety function (power interruption to the motor) is maintained. Also, the system does not restart because NO contact of K3 does not shut, therefore K1 and K2 cannot be ener- gized. (090319)
