How to connect STO signals
Please refer to the wiring examples below for wirings on
terminals.
■
Wiring
e.g. Internal power Source logic
*) Please connect between STC and CMS.
4.4.3
Input terminal
Input signals of Safety function are redundant inputs of
terminal group -1 and terminal group -2.
When voltage is applied to each input, currents flow on
each safety path inactivating the Safety function.
When voltage is removed from at least one of the
redundant inputs, the Safety function is activated by the
corresponding safety path.
The voltage source for input signals of safety function is
selectable from the 24V power supply for input terminals
(P24E) or an externally prepared DC24V power supply.
The external power supply must be SELV or PELV DC24V
power supply.
An example of wiring the switch to input S1-1 and S1-2 is
shown below.

In case of use of the 24V power supply for input
terminals (P24E)
