The 24 V DC input and 24 V DC output with a 3 A rating delivers a predictable hold-up solution, reducing unplanned outages and safeguarding critical control logic. This translates to measurable business benefits like improved line uptime, stable PLC performance, and lower risk of data loss during transient events. The CP-B buffer module’s energy storage of 1000 Ws enables longer hold-up times for essential loads, supporting safe shutdown sequences and orderly process stabilization in automation cabinets. Its IP20 protection, flexible connection options (0.08 to 1.5 mm² wire range), and DIN rail mounting (TH35-15 or TH35-7.5) simplify installation and maintenance, reducing commissioning time and spare part needs. Industry-grade standards ensure compatibility with CAN/CSA, IEC 61000 series, and UL 508 environments, addressing common compliance concerns. In practice, engineers gain a compact, scalable solution that integrates with existing 24 V automation ecosystems, improving overall system resilience and return on investment.

FAQs
Install on TH35-15 or TH35-7.5 DIN rails per ABB instructions, ensuring secure mechanical mounting and proper clearance. Use flexible ferrule or rigid wire 0.08–1.5 mm² on input and output terminals, tighten to recommended torque, and observe IP20 protection when panel doors are closed.
It delivers 24 V DC hold-up with 1000 Ws energy storage, supports operation from -40 to +60 °C, and mounts on standard DIN rails, enabling compact, robust integration in control cabinets while meeting industrial standards such as UL 508 and EN/IEC noise immunity requirements.
Yes. The module carries UL 508 certification and CE/UKCA declarations, aligning with US/Canada safety requirements and European market conformity for reliable deployment in mixed regulatory environments.
Typical use cases include PLC hold-up during short power dips, safe machine shutdown sequencing, and interference-free control of equipment in automation cells, workstations, and distributed control systems that rely on stable 24 V power to preserve process data.
With a compact form factor and solid-state energy storage, maintenance typically centers on ensuring proper terminal connections, verifying DIN rail integrity, and periodic inspection of the enclosure for dust ingress. Benefits include reduced downtime, longer equipment lifecycle, and lower risk of unscheduled outages.
