The Allen-Bradley 1756-A7/B ControlLogix® Chassis serves as the robust backbone for high-performance automation systems, providing 7 slots for ControlLogix processors, I/O modules, and communication interfaces. Engineered with heavy-gauge steel construction and zinc-plated hardware, it delivers NEMA 12/4X (IP65) protection against dust, oils, and corrosive agents.
Featuring integrated cooling fins and vibration-dampening mounts, it operates reliably from -40°C to +70°C in harsh environments like mining or offshore platforms. The chassis supports dual power supplies for redundancy and includes EMI-shielded backplane connectors to maintain signal integrity.
- Slot Capacity: 7 slots (1 controller + 6 modules)
- Backplane Bandwidth: 256 Gbps via PCIe-based architecture
- Power Distribution: Dual 24V DC inputs (5A max per slot)
- Isolation: 1500V AC isolation between slots
- Cooling: Natural convection (0.5°C/W thermal resistance)
- Vibration/Shock: 5g @ 5-150Hz (IEC 60068-2-6) / 30g @ 11ms (IEC 60068-2-27)
- Environmental: 0-95% non-condensing humidity / UL Type 4X/12
- Certifications: ATEX II 3G, IECEx, DNV-GL, UL 61010-1, RoHS III
