Through its design, the SITOP PSE200U selectivity module enables simple replacement of miniature circuit breakers. Electronic protection offers a variety of advantages over electromechanical protection.
Monitoring
The current per output is monitored by the selectivity module; if the set threshold of the output is exceeded, the output is switched off according to a predefined time-current characteristic curve. All other feeders continue to be supplied without interruption. In addition to the output currents, the supplying 24 V input voltage is also continuously monitored. As soon as this voltage threatens to fail, the path with a higher current than the set threshold is disconnected immediately.
Signaling
Signaling of the faulty feeder takes place via the LEDs on the device as well as via a signaling contact. The SITOP PSE200U selectivity modules are available as a variant with common signaling or single-channel signaling. Single-channel signaling outputs the status (connected, disconnected due to overload) of the individual outputs cyclically by means of a serial code which can be read in by a digital PLC input.
Free function blocks for SIMATIC S7-300/400/1200/1500 for STEP 7 and TIA Portal as well as SIMOTION CPUs with SIMOTION SCOUT are available for evaluation. This enables simple integration into the S7 diagnostics and higher-level operator control and monitoring systems.

Easy visualization in the SIMATIC PCS 7 process control system is made possible by the SITOP library, which contains function blocks and faceplates for single-channel and common signaling.
Connection and disconnection of the outputs
To reduce the inrush peak current and relieve the power supply, the individual outputs can be switched on sequentially with a pre-defined delay time or load-dependent when the device starts up. Each output can be manually connected and disconnected via buttons on the device (for example, for commissioning or service). Disconnected outputs can also be connected by means of remote reset (24 V input). The prerequisite is that the outputs were not disconnected manually on the device.
