Siemens SITOP UPS1100 Battery Module 6EP4134-0GB00-0AY0

The Siemens SITOP UPS1100 battery module (article number 6EP4134-0GB00-0AY0) is a maintenance-free sealed lead-acid battery module designed for use with SITOP DC UPS modules. This 24 V DC, 7 Ah battery module provides uninterruptible power supply functionality for industrial control systems, ensuring that PLCs, HMIs, sensors, and other automation components continue to operate during mains power interruptions or voltage fluctuations. The UPS1100 series is part of Siemens' comprehensive SITOP power supply portfolio, engineered for industrial reliability and performance.

Technical Specifications

The battery module has a rated voltage of 24 V DC and a capacity of 7 Ah. The sealed lead-acid battery is maintenance-free, eliminating the need for periodic electrolyte checks or refills. The module operates with SITOP DC UPS modules such as the SITOP UPS1600 (6EP4134-3AB00-0AY0) or SITOP UPS1100 series uninterruptible power supplies. The module is housed in a robust metal casing designed for DIN rail mounting. Operating temperature range is -10°C to +50°C; storage temperature range is -40°C to +70°C. Dimensions: approximately 120 mm (H) × 60 mm (W) × 125 mm (D). The module includes status LED indicators for charge state and battery fault. The battery is protected against deep discharge by the connected UPS module, which automatically disconnects the battery when the voltage falls below the safe threshold.

Compatibility and Integration

The 6EP4134-0GB00-0AY0 battery module is designed for use with Siemens SITOP UPS1600 (6EP4134-3AB00-0AY0) and SITOP UPS1100 series DC UPS modules. The UPS module monitors the battery status, controls charging, and provides diagnostic information to the PLC via communication interfaces (Modbus RTU, PROFIBUS, PROFINET). The battery module connects to the UPS module via a two-wire cable (included or ordered separately). The UPS module performs automatic temperature-compensated charging to maximize battery service life. When mains power is present, the UPS module maintains the battery at full charge. During a power failure, the UPS module seamlessly switches to battery power, providing uninterrupted 24 V DC output for the connected loads. The UPS module also provides buffering against voltage dips and short-term interruptions without switching to battery.

Applications

This battery module is used in industrial applications where uninterrupted operation is critical to prevent data loss, equipment damage, or production downtime. Typical applications include:

• Powering PLC systems (S7-1200, S7-1500, S7-300) during power interruptions

• Supporting HMI and SCADA systems for continued operator visibility

• Buffering industrial PCs and servers

• Maintaining communication networks (switches, routers) during outages

• Orderly shutdown of automated processes to prevent product waste

• Backup power for safety systems and emergency lighting

Installation and Maintenance

Mount the battery module on a 35 mm DIN rail in a control cabinet. Connect the battery module to the SITOP UPS module using the provided cable or a suitable two-wire cable (minimum 1.5 mm²). Observe correct polarity. No other wiring is required; the UPS module manages all battery functions. The battery module is maintenance-free, but periodic functional testing is recommended. Perform a battery test using the green button on the UPS module or via the UPS interface to verify that the battery can deliver the required backup time. The UPS module monitors battery capacity and age; when the battery reaches the end of its service life (typically 3-5 years depending on operating conditions), the UPS module signals a "battery fault" via LED and communication interface. Replace the battery module at that time.

Environmental and Compliance

The SITOP UPS1100 battery module is CE, UL, and RoHS compliant. Operating temperature: -10°C to +50°C (with appropriate UPS module). Humidity: 5-95% non-condensing. The module meets IP20 protection rating and must be installed in a control cabinet. The sealed lead-acid battery is subject to hazardous goods regulations for transport; consult local regulations for disposal at end of life.

Conclusion

The Siemens SITOP UPS1100 6EP4134-0GB00-0AY0 battery module provides a reliable, maintenance-free power backup solution for industrial control systems. When paired with a SITOP DC UPS module, it ensures continuous operation of critical automation components during mains power interruptions, protecting production processes and preventing data loss.
