Connection of Load Circuit:
• When the frequency of operation is rather high, in the case of
proportional operation for instance, maximum load with
respect to the capacity of the output relay will result in shorter
life. Use an auxiliary relay in such a case. Type SSR is
recommended.
electromagnetic switch: proportion cycle 20 sec. and above
SSR:
proportion cycle 2 sec. and above
(approximately)
contact output life: mechanical: 10 million times (no load)
electrical:
100 thousand times (nominal
load)
• Relay contacts will be worn out with time. After certain period
has passed, locking (a phenomenon in which a contact cannot
be released once switched on) may happen. It is advisable to
provide an external safety device to protect the system just in
case locking happens.
