The Siemens 6EP1961-3BA21 is a SITOP PSE202U redundancy module engineered to enhance the reliability of 24V DC power supply systems. This essential accessory allows decoupling of two power supply units, ensuring the connected load remains powered by the second unit if one unit fails. Capable of handling up to 40A, it is a critical component for mission-critical applications where downtime is not an option. Its sleek DIN-rail mounting design makes it easy to integrate into standard control cabinets.

Why Buy the Product? Investing in this Siemens 6EP1961-3BA21 redundancy module prevents costly system shutdowns by maintaining a continuous power flow during individual supply failures. It provides peace of mind through automated power backup and real-time status monitoring via signal contacts.
