Note) X0 through X5 are inputs for the high-speed counter and have a fast response time. If used as
normal inputs, you are recommend to insert a timer in the ladder program as chattering and
noise may be interpreted as an input signal.
Also, the above specifications apply when the rated input voltage is 24V DC and the temperature
is 25 ºC.
