(circuits for emergency lamps, alarm devices and error inspection that, for example, revert only during malfunction and output warnings with form B contacts) Continuous, long-term current to the coil will facilitate deterioration of coil insulation and characteristics due to heating of the coil itself. For circuits such as these, please use a magnetic-hold type latching relay. If you need to use a single stable relay, use a sealed type relay WKDWLVQRWHDVLO\DHFWHGE\DPELHQWFRQGLWLRQVDQGPDNHDIDLOVDIH circuit design that considers the possibility of contact failure or disconnection. Temperature rise due to pulse voltage When a pulse voltage with ON time of less than 2 minutes is used, the coil temperature rise bares no relationship to the ON time. This varies with the ratio of ON time to OFF time, and compared with continuous current passage, it is rather small. The various relays are essentially the same in this respect. Current passage time (%) For continuousu passage Tempereture rise value is 100% ON : OFF = 3 : 1 About 80% ON : OFF = 1 : 1 About 50% ON : OFF = 1 : 3 About 35% DC Coil operating power ON : OFF = 1 : 1 Voltage Steady state DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. +RZHYHUSOHDVHFKHFNZLWKWKHDFWXDOFLUFXLWVLQFHWKHHOHFWULFDO characteristics may vary.

Maximum allowable voltage and temperature rise Proper usage requires that the rated coil voltage be impressed on the coil. Note, however, that if a voltage greater than or equal to the maximum continuous voltage is impressed on the coil, the coil may burn or its layers short due to the temperature rise. Furthermore, do not exceed the usable ambient temperature range listed in the catalog. Maximum allowable voltage for coil In addition to being a requirement for relay operation stability, the maximum continuous impressed coil voltage is an important constraint for the prevention of such problems as thermal deterioration or GHIRUPLW\RIWKHLQVXODWLRQPDWHULDORUWKHRFFXUUHQFHRIUHKD]DUGV In DC relays, after continuous passage of current in the coil, if the current is turned OFF, then immediately turned ON again, due to the WHPSHUDWXUHULVHLQWKHFRLOWKHSLFNXSYROWDJHZLOOEHFRPHVRPHZKDW higher. Also, it will be the same as using it in a higher temperature atmosphere. The resistance/temperature relationship for copper wire is about 0.4% for 1C, and with this ratio the coil resistance increases. That is, in order to operate of the relay, it is necessary that the voltage EHKLJKHUWKDQWKHSLFNXSYROWDJHDQGWKHSLFNXSYROWDJHULVHVLQ accordance with the increase in the resistance value. However, for some polarized relays, this rate of change is considerably smaller.

Others Cleaning 1) Although the environmentally sealed type relay (plastic sealed type, etc.) can be cleaned, avoid immersing the relay into cold liquid (such as cleaning solvent) immediately after soldering. Doing so may deteriorate the sealing performance. 2) Surface mount terminal type relay is sealed type and it can be cleaned by immersion. Use pure water or alcohol-based cleaning solvent. 3) Cleaning with the boiling method is recommended (The temperature of cleaning liquid should be 40C or lower). Avoid ultrasonic cleaning on relays.
