Part numbers without protection elements 1) 1 V models When connecting a coil surge protection circuit to these relays, we recommend a zener diode with a zener voltage of V or higher, or a resistor (Ω to 1,Ω). When a diode is connected to the coil in parallel, the release time will slow down and working life may shorten. Before use, please check the circuit and verify that the diode is not connected in parallel to the coil drive circuit. ) V models When connecting a coil surge protection circuit to these relays, we recommend a zener diode with a zener voltage of V or higher, or a resistor (,Ω to,7ω). When a diode is connected to the coil in parallel, the release time will slow down and working life may shorten. Before use, please check the circuit and verify that the diode is not connected in parallel to the coil drive circuit.. Part numbers with diodes These relays use a diode in the coil surge protection element. Therefore, the release time is slower and the working life might be shorter compared to part numbers without protection elements and part numbers with resistors. Be sure to use only after evaluating under actual load conditions. 3. Part numbers with resistors This part number employs a resistor in the coil surge protection circuit; therefore, an external surge protection element is not required. In particular, when a diode is connected in parallel with a coil, the release time becomes slower which could adversely affect working life. Please check the circuit and make sure that a diode is not connected in parallel with the coil drive circuit. For Cautions for Use, see Relay Technical Information.
