• The expected life span of relay

The relay used in MASTER-K10S1 is FUJI's RB1-E, and those manufacturer
guarantee 10million times (mechanical) and 0.1 ~ 3million times (electrical)
operation for their relays..
The durability of relay depends on the type of external load. Therefore, we highly
recommend customers to connect an external relay or SSR between PLC and
large inductive load for improved reliability and maintenance of PLC. The capacity
of external relay or SSR should be at least twice larger than the capacity of the
load.
• All outputs will be turned off when interruptions of CPU control, voltage drops /
interruptions, and/or power up/down occur.
• Improper terminal connection or overloads on I/O may cause a damage on the
internal devices.
