6EP1962-2BA00 | Siemens Redundancy Module for Control Power

Product Overview

The Siemens 6EP1962-2BA00 is a SITOP PSE202U redundancy module for 24 V DC power systems.
It enables secure decoupling of two independent SITOP power supplies feeding one critical load.
Moreover, the module improves system availability by preventing single power supply failures from interrupting operation.
Therefore, automation systems continue operating reliably even when one power source becomes unavailable.

This redundancy module follows NEC Class 2 requirements, limiting output power to 100 VA.
In addition, Siemens designed it for compact control cabinets where space efficiency remains essential.

Functional Highlights

The module automatically balances current between two connected SITOP power supplies.
Moreover, internal decoupling electronics prevent reverse currents and cross-loading conditions.
Therefore, each power supply operates independently without mutual interference.
Integrated diagnostics support faster fault localization during maintenance activities.
