When the PLC controls operation such as the clockwise and counterclockwise operation of a motor and
if there is any possibility of an accident or mechanical damage due to faulty PLC operation, provide an
external interlock such as the one shown below to prevent both the forward and reverse outputs from
turning ON at the same time.
Example:
External Interlock Circuits
A circuit like the one shown in the dia-
gram on the left is required to prevent
outputs MC1 and MC2 from both being
ON at the same time even if both PLC
outputs CIO 100.00 and CIO 100.01
are both ON.
