Siemens SITOP PSE202U Redundancy Module, 24VDC / 40A, Hazardous Location Rated  6EP1961-3BA21

The Siemens SITOP PSE202U Redundancy Module 6EP1961-3BA2 is a critical component for enhancing the reliability of 24VDC power supply systems in industrial automation. Designed to decouple two SITOP power supplies each with an output current of up to 20A, this module ensures continued power supply to critical loads even if one power supply fails, thereby increasing system availability.

This redundancy module operates with a DC 24V input and provides an output capacity of up to 40A. It is suitable for use in a wide ambient temperature range of 0°C to 60°C. A key feature is its certification for use in various hazardous locations, including cULus Listed for Class I Division 2, Groups A, B, C, D and Class I Zone 2, Group IIC, as well as ATEX 94/9/EC for Class I, Zone 2. This makes it suitable for applications in potentially explosive atmospheres.

The SITOP PSE202U also includes signaling capabilities to indicate the operational status of the power supplies, often via relay contacts. Its compact design and standard mounting make it easy to integrate into control cabinets. The warning on the label regarding threshold adjustment highlights the importance of proper configuration during initial installation.
