Add to Cart
The Allen-Bradley 1756-A7/B ControlLogix® Chassis provides a rugged modular foundation for mission-critical automation systems. Designed to house ControlLogix processors, I/O modules, and communication interfaces, this 7-slot chassis features heavy-gauge steel construction with zinc-nickel plating for corrosion resistance in harsh environments. With integrated cooling fins and vibration-dampening mounts, it operates reliably from -40°C to +70°C while meeting NEMA 4X/IP66 standards for protection against dust, oils, and moisture. The PCIe-based backplane enables 40 Gbps data transfer speeds, supporting deterministic control and redundant power configurations (up to two 1756-Px power supplies). Tool-less module clamps facilitate rapid deployment and maintenance in industrial settings.
