Product Description

• The Siemens SITOP PSE200U 6EP1961-2BA11 is a four-channel electronic selectivity module designed to distribute and protect 24V DC power circuits in industrial electrical control systems.
• Part of the Siemens SITOP power supply accessory family, this module provides selective electronic protection of individual downstream loads connected to a common DC power supply.
• The module is designed for use in industrial automation installations where multiple control circuits share a central 24V DC supply. By monitoring each output channel individually, the PSE200U helps prevent an overload or short circuit on one connected load from interrupting power to other properly operating circuits.
• Each of the four outputs is independently adjustable over a current range of 0.5A to 3A. The combined rated output current is 12A when all four channels are configured for their maximum rated current, provided the supplying power source has sufficient capacity.
• The device operates from a nominal 24V DC input, with an allowable voltage range of 22–30V DC. The output voltage follows the input supply voltage with a typical internal voltage drop of approximately 0.2V.
• Electronic current monitoring and current limitation allow the module to identify and disconnect overloaded or short-circuited branches. Its current-limiting characteristic is designed to support selective shutdown while maintaining operation of unaffected circuits.
• Four three-color status indicators provide individual channel information. Green identifies an enabled output, yellow indicates a manually disabled output, and red indicates shutdown caused by overcurrent.
• Each output can be switched on and off using its dedicated front-panel control. The module also provides a remote reset input for restoring eligible channels through an appropriate external 24V DC control signal.
• The 6EP1961-2BA11 includes a common signaling changeover contact for monitoring the module from compatible automation systems, indicator devices, or other control equipment.
• Selectable connection delays allow the output circuits to be energized with delays of 0ms, 25ms, or 100ms, or through the manufacturer's load-optimized sequential connection function.
• These functions can help manage startup conditions and reduce simultaneous inrush demand when multiple DC loads are connected to the same supply.
• The module provides approximately 97% efficiency at rated operating conditions and uses passive convection cooling without a dedicated cooling fan.
• Its compact enclosure measures approximately 72mm wide, 80mm high, and 72mm deep. The housing mounts onto standard 35mm DIN rails conforming to EN 60715 and is intended for installation inside suitable industrial electrical cabinets.
• The device uses screw-type electrical terminals for DC power input, protected outputs, remote reset, and common signaling connections.
• Siemens specifies an ambient operating temperature range of -25°C to +60°C, with appropriate installation clearances and environmental conditions.
• The PSE200U also carries applicable industrial safety and hazardous-location approvals, with manufacturer documentation identifying marine-related approvals including ABS and DNV.
• The Siemens 6EP1961-2BA11 is an electronic circuit selectivity and distribution module, not an independent AC/DC power supply. It requires a compatible regulated 24V DC power source.
• For proper installation, buyers should verify input power capacity, branch circuit current settings, wiring requirements, startup behavior, and protective coordination according to Siemens technical documentation.
