SITOP PSE200U

The selectivity and diagnostics modules are the optimum enhancement for all 24V
power supplies to distribute the load current to several feeders and to monitor it.
The module detects an overload or short-circuit in one or more feeders and shuts
them down as needed. This is ensured even on high-resistance lines and in the
case of "creeping" short-circuits. The intact feeders continue to supply the SITOP
selectivity modules with 24 V on an absolutely interruption- and reaction-free
basis. Their signal contact can be looped across several selectivity modules and
can be evaluated as a common alarm in SIMATIC PCS 7.
