The life under the worst conditions, of the output contacts used in
ZEN relay outputs is given in the above table. Guidelines for the
normal life of the relays are shown in the diagram on the right.
Life-test Curve (Reference Value)
Usage: 360 times/hour
Note:
The switching capacity, switching durability, and applicable
load area when actually using the relay depend on the type of
load, environmental conditions, and switching conditions.
Therefore, be sure to confirm these conditions for the actual
machine before use.
