Fig. 12-4: Signal Detection at Probe Input
Probe inputs are inputs used to acquire fast digital input signals.
For
control
use bounce-free
switching
elements
(e.g. electronic
switches) to avoid incorrect evaluation.
External Power Supply
At
the
pins
1
and
3 of the connectors X37 and X38, you can connect an
external 24 V power supply to increase the maximum output current of the
digital outputs. The external 24 V supply must comply with a voltage
tolerance of ±20%.
