Consequences



Plant standstill due to drop in 24 V power
Trouble-shooting much more difficult
Long standstill times
Reason for undesired triggering during operation


Excessive current peaks during startup
Consequence

Malfunction, machine/plant switches off

Circuit diagram
Characteristic
Fault paths are powered down reliably even under very
poor operational conditions.



Retension of the 24 V power for all other paths
Plant down time is reduced or even avoided.
Fast trouble-shooting and fault localization
Device features
Data
Loads with high startup current peaks power up with
current limitation.

Malfunction-free device startup

Selectivity and fast error diagnosis of 24 V feeder circuits


Four feeder circuits (outputs) per module
Each output can be set between 2 and 10 A using
potentiometer.
 Multi-color LED for each output for rapid fault localization
 Potential-free common signal contact for fault diagnosis
 Several modules can be connected to a single power supply.
 Simple and rapid installation using standard mounting rail
 Additional line protection and gradual equipment

From set value up to 130%
 switch off after approx. 5 sec
Above 130% of set value
 current limiting to 130% for 50 to
