Max. operating speed
Notes:
*1. This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.
*2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport
Conditions“ in
AMBIENT ENVIRONMENT section in Relay Technical Information.
Please inquire if you will be using the relay in a high temperature atmosphere (110C
230F).
*3. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you confirm operation under actual conditions.
If the relay is used continuously for long periods of time with coils on both sides in an energized condition, breakdown might occur due to abnormal heating depending on
the carrying condition. Therefore, please inquire when using with a circuit that causes an energized condition on both sides simultaneously.
