Siemens 6EP1931-2FC21 | SITOP Redundancy Module – 24V DC, 40A for Parallel Power Supply Systems
Overview
The Siemens 6EP1931-2FC21 is a redundancy module from the SITOP series, designed to connect two 24V DC power supplies in parallel, ensuring uninterrupted power even if one supply fails. With a current rating of up to 40A, this DIN rail-mounted module is ideal for high-availability industrial systems, using diode-based decoupling to prevent feedback between connected supplies.
