The ABB 086348-001 is a PWA (Printed Wiring Assembly) End Column Frame (ECF) designed specifically for securing the terminal end of ABB industrial control system racks, providing structural stability, electrical isolation and mechanical protection for module columns in automation cabinets. As a critical rack component, it prevents module displacement caused by vibration, maintains signal integrity between adjacent modules and serves as a grounding point for the rack assembly. Engineered for ABB control system racks including AC500, Advant Controller 400 and Freelance DCS, it ensures precise alignment of I/O modules, power supplies and communication cards while simplifying system expansion and maintenance. The compact, lightweight design (0.21 kg) integrates seamlessly with standard ABB rack dimensions, offering a cost-effective, reliable solution for industrial automation infrastructure.

The 086348-001 features a rigid, lightweight metal alloy frame with corrosion-resistant coating, providing structural reinforcement for control system racks while minimizing weight impact on cabinet load capacity. It incorporates precision-machined mounting points for secure attachment to ABB rack rails, ensuring consistent module alignment and preventing connection errors during installation. The integrated PWA (Printed Wiring Assembly) provides electrical isolation between the end column and adjacent modules, reducing cross-talk and interference in high-density rack configurations. It includes dedicated grounding terminals for establishing proper rack grounding, enhancing system EMC performance and protection against electrical surges. The design supports hot-swappable module replacement without removing the end column, maximizing system uptime during maintenance.

The 086348-001 End Column Frame is designed for tool-free installation on standard ABB control system racks, with snap-in mounting clips that secure the frame to rack rails without additional hardware. It is fully compatible with ABB AC500 PLC racks, Advant Controller 400 system racks, Freelance DCS racks and other ABB automation system chassis, providing a unified end column solution for ABB control infrastructure. The frame accommodates various ABB I/O modules, communication modules, power supplies and specialty modules, supporting high-density rack configurations in industrial control cabinets. It maintains compatibility with ABB rack accessories including blanking plates, cooling fans and cable management systems, ensuring a complete, integrated rack solution for industrial automation applications.
