The Siemens SITOP PSE200U is a 4-channel selectivity module designed for 24V DC power distribution in industrial automation, manufacturing, and control panel applications. Part number 6EP1961-2BA21, this module accepts a single 24V DC input at up to 40A and distributes it across four independently adjustable output channels, each rated at 24V DC and up to 10A. The current threshold for each output is adjustable between 3 and 10A via individual potentiometers, allowing precise overload protection tuning for each branch circuit.
In the event of an overload or short circuit on one or more outputs, the module disconnects only the affected feeder while maintaining uninterrupted 24V supply to all remaining channels. This selective shutdown capability prevents a single fault from causing a complete system outage, a common failure mode when branch circuits are protected by standard miniature circuit breakers alone.
The module includes a common signaling contact for group fault indication, three-color LED status indicators for each channel, and an ON/OFF/RST pushbutton for manual control and reset. It mounts on standard DIN rail and uses screw-type terminals for wiring connections. Operating temperature range is rated from minus 25 to plus 60 degrees C in free convection.
Certifications visible on the nameplate include UL Listed, CSA, CE, EAC, DNV-GL, ATEX (EPS 9 ATEX 1 169X), and IECEx (EPS 14.0067X) for Class I, Division 2, Groups A through D, T4, and Zone 2 hazardous location use. Manufactured by Siemens AG Austria. Serial number 06M6AC3VGU7.
