Technical data
Supply
The safe input and the output are isolated and designed for a low−voltage supply through
a safely separated power supply unit (SELV/PELV) of 24 V DC. P/N switching input signals
and test pulses
£
1 ms are permissible.
Active sensors are directly connected to the X61 circular connector.
Passive sensors are connected to the X61 circular connector via a switching device. The
switching device must comply with the required performance level of the application.
There is no monitoring for short circuits.

Note!
Safe inputs have two channels (...A/...B). The channels must be triggered
separately and simultaneously (equivalent).
Active triggering of only one channel indicates faulty sensors or impermissible
wiring.
Despite this, the integrated safety system is activated as soon as at least one
channel has been triggered.
