10.5 Technical data
Supply
The inputs and outputs 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 wired to the X80 terminal strip.
Passive sensors are wired to the X80 terminal strip via a switching device. The switching
device must comply with the required control category of the application.
There is no monitoring for short circuits.
