Automation and Drives
Reasons for selective triggering failure when fault occurs Long load lines Creeping short circuits Line circuit breakers dimensioned too large
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

The solution
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
Loads with high startup current peaks power up with current limitation.
Malfunction-free device startup

The solution
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
commissioning with exchangeable FK2 blade-type fuse

Irated can be adjusted from 2 to 10 A per output circuit. Characteristics per currentrequirements depend on the output circuit.
From 0 A to the set value ( I/ Irated=100%) without switching off From set value up to 130% switch off after approx. 5 sec Above 130% of set value current limiting to 130% for 50 to
100 msec, next switch off Over the set value with simultaneous
collapse of the supply voltage below 20V immediate switch off
