The Beckhoff CU8110-0120 is a capacitive uninterruptible power supply (UPS) module designed to safeguard automation systems against short-term power interruptions. Built on EDLC (Electric Double Layer Capacitor) technology, this UPS offers a highly durable, maintenance-free energy storage solution for industrial environments where reliability and minimal downtime are essential.

Delivering 110 W of backup power with a capacity of 0.9 Wh, the CU8110-0120 provides just the right amount of energy to bridge power dips or outages, allowing systems to maintain stable operation long enough to shut down safely or ride through short disturbances. Its 24 V DC input and output (with a tolerance of -15%/+20%) make it ideal for seamless integration into existing industrial power systems, ensuring compatibility with a wide range of controllers, I/O devices, and automation hardware.

The use of EDLC capacitive storage offers distinct advantages over traditional battery-based UPS systems. Unlike batteries, EDLC capacitors have extremely long service lives, require no routine maintenance, and can withstand a high number of charge and discharge cycles. This ensures that the CU8110-0120 delivers dependable performance across years of continuous operation, even in harsh industrial conditions.

The module’s metal housing and compact form factor are engineered for straightforward installation on a standard TS35x15 DIN rail, saving valuable control cabinet space. Robust construction protects the unit from environmental stresses, making it suitable for use in demanding production and process automation environments.

For ease of monitoring and diagnostics, the CU8110-0120 is equipped with three clear status LEDs: one each for input voltage (UIN), output voltage (UOUT), and diagnostic/fault indication (DIAG). These visual indicators allow technicians and operators to quickly verify system status at a glance, supporting rapid troubleshooting and ensuring minimal downtime.

Installation is simplified through the push-in dual 9-pin plug connectors, which provide a secure and user-friendly wiring interface. This design reduces installation time while ensuring reliable electrical connections, a critical factor in maintaining consistent system performance.

The CU8110-0120 is ideally suited for applications where even brief power interruptions could cause system faults, data loss, or process disruption. It ensures that sensitive control electronics remain powered through short outages, allowing systems to complete critical processes or transition to a safe shutdown without risk to data integrity or hardware.

In summary, the Beckhoff CU8110-0120 UPS Module combines advanced capacitive storage technology with robust industrial design and user-friendly features. Offering 110 W of dependable backup power, straightforward diagnostics, and long service life without maintenance, it provides an efficient and reliable safeguard against the unexpected, making it an excellent choice for modern industrial automation systems.
