[Input circuit]
* N: I/O24V power connector, 0V
Caution
If a non-contact circuit is connected externally, malfunction may result from leakage
current. Use a circuit in which leakage current in a switch-off state does not exceed 1
mA.

X-SEL controller’s input signal
At the default settings, the system recognizes the ON/OFF durations of input signals if they
are approx. 4 msec or longer. The ON/OFF duration settings can also be changed using I/O
parameter No. 20 (input filtering frequency).
