Technical data of the D4x5-2

5.5 Interfaces and performance features

Note
If the D4x5‑2 detects undervoltage, the module performs a RESET. If all LEDs are off, either
there is no power supply or the voltage level is too low.
When the voltage level is in the permissible range again, the D4x5‑2 restarts.
Undervoltages are detected when:
● The voltage level of the 24-V supply falls below the minimum permissible input voltage of
● A temporary voltage dip (> 3 ms) results in the supply falling below the minimum
