Technical data
Supply
The inputs 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 X1 terminal strip.
Passive sensors are wired to the X1 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.
