6EP1961-2BA31 SIEMENS

The SITOP PSE200U 3 A selectivity module (6EP1961-2BA31) is a four-channel device designed for selective monitoring of 24 V DC power supply circuits. It safeguards against overloads and short circuits in individual branches, ensuring the reliable operation of connected loads. This module features an input voltage of DC 24 V with a current capacity of 12 A. Each of the four output channels provides a 24 V DC supply and can deliver a maximum current of 3 A. The tripping current for each channel is adjustable within a range of 0.5 to 3 A, allowing for customized protection based on the specific requirements of the connected devices. In the event of an overload or short circuit, the affected channel is selectively disconnected, preventing a complete system shutdown. A status message is provided for each output, indicating the condition of the channel (e.g., normal operation, overload, or short circuit). This detailed feedback enables quick identification and resolution of issues, minimizing downtime. The SITOP PSE200U enhances system availability by preventing the propagation of faults and ensuring that only the affected circuit is isolated. Its compact design and user-friendly interface make it easy to integrate into existing power distribution systems.
