Notes on Correct Use
1. Notes on contact load
2. Driving relays
- If the internal connection diagram of a relay shows + and – symbols on the coil, apply the rated voltage to the
- The maximum voltage that can be applied to the coil of the relay varies depending on the ambient
- If the driving voltage waveform of the relay coil rises and falls gradually, the inherent performance of the
- For a latching relay, apply a voltage to the coil according to the polarity specified in the internal connection
- If a current is applied to the coil over a long period of time, the coil temperature rises, promoting generation of
- The operating time and release time indicate the time required for each contact to close after the voltage has
3. Operating environment
- Make sure that the relay mounted in the application set is used within the specified temperature range. Use
- If the relay is used for a long period of time in highly humid (RH 85% or higher) environment, moisture may

condensation.
Make sure that the contact load is within the specified range; otherwise, the lifetime of the contacts will
be shortened considerably. Note that the running performance shown is an example, and that it varies
