Overview
The Siemens 6EP1961-2BA31 SITOP PSE200U selectivity module is an industrial-grade power distribution accessory designed for 24V DC systems. The SITOP PSE200U selectivity module is the optimal addition to all 24 V power supplies for distributing and monitoring the load current across several branch circuits. This module enables engineers to split a single 24V power supply output across multiple load circuits while maintaining independent fault detection and protection on each channel.
Key Features
- Four output channels, each with an adjustable current threshold ranging from 0.5A to 3A, and provides individual status indicators for precise monitoring.
- Overload and short-circuit in one or more feeders are reliably detected. De-energize feeders with longer overload.
- The intact feeders continue to be supplied with 24 V without any interruption or disturbance, thereby minimizing plant downtimes.
- The faulty feeder is signalled using LEDs and a group signal contact.
- Sealable transparent cover over adjusters for currents and times protects against maladjustment (PSE200U)

- Applications requiring independent overload and short-circuit detection across multiple loads
Compatibility & Replacements
Compatible With
- All standard Siemens SITOP PSE200U 24V DC power supplies
- Industrial automation control panels with 24V DC bus
- DIN rail-mounted power distribution systems
- PLC, HMI, and drive control circuits requiring selective load isolation
Replaces / Drop-In Replacement For
6EP1961-2BA11 and 6EP1961-2BA31 are listed in the same selectivity module product family. The 6EP1961-2BA31 specifically replaces other 3A selectivity modules within the PSE200U line requiring identical current handling and threshold adjustment. Verify your existing module part number before ordering.
Works With
