■ Overview
SITOP select
■ Application
The diagnosis module is used together with 24 V power supply units to divide the load current between
several branch circuits and to monitor the individual currents. Faults in the individual circuits
resulting from an overload or short-circuit are detected and switched off selectively, and other load
current paths therefore remain unaffected by the fault. This results in rapid fault diagnostics, and
downtimes are minimized.
