APCBU85A1/1
The B & R Automation APCBU85A1/1 is part of the APC Industrial Automation PC Units series, engineered by B & R Automation for industrial computing applications. This chassis-mounted unit features a Rated Voltage of 85V and a Current Rating of 1A, ensuring stable power delivery even under load. Equipped with a Form Factor of 4 x ISA slots, it supports hardware expansion and legacy card integration. Its primary function is to serve as a robust backplane assembly for factory-floor PC systems, enabling seamless integration of control and I/O modules in harsh environments.
Designed around a multi-layer board constructed from Fiberglass PCB with solder mask, the APCBU85A1/1 ensures high signal integrity and mechanical resilience. The horizontal parallel layout of its four ISA expansion slots allows for compact device stacking, while the Gold-Finger edge connector interface guarantees reliable, low-resistance mating with the motherboard. An onboard Dielectric Withstanding Voltage rating of 1500V AC and a minimum Insulation Resistance of 1000 MΩ underscore its electrical robustness. The unit mounts securely via chassis screw points, providing a vibration-resistant platform for embedded control systems.
Built for industrial longevity, the APCBU85A1/1 offers broad environmental tolerance from –40 °C to +85 °C and an IP67 ingress protection rating, shielding internal components from dust and moisture. Compliance with the PICMG 1.0 backplane standard is clearly indicated by visible marking, ensuring compatibility with legacy and modern embedded systems. Standard AT power connector and wire gauge range support (22–14 AWG) simplify installation and maintenance. This backplane module delivers exceptional durability, electrical stability, and expansion flexibility—ideal for retrofit projects, automated production lines, and critical machinery requiring uninterrupted operation.
