Allen-Bradley 1756-A13 ControlLogix 13-Slot Chassis

Allen-Bradley 1756-A13 ControlLogix 13-Slot Chassis is a standard, open-style backplane enclosure designed to host up to thirteen ControlLogix modules in a single 13-slot chassis. The backplane provides a high-speed communication path between installed modules, forming the core of a modular ControlLogix system. The chassis dimensions are 588 mm wide, 169 mm high, and 145 mm deep (23.15 in x 6.65 in x 5.71 in), and it weighs about 1.9 kg. Electrical specifications include backplane power rails at 1.2 VDC capable of 1.5 A per chassis, 3.3 VDC up to 4 A, and a 5.1 VDC rail with up to 15 A total (6 A per slot); a 24 VDC rail up to 2.8 A. The unit dissipates about 6.1 BTU/hr with typical power consumption around 1.8 W. This chassis is designed for ControlLogix architectures and is compatible with standard 1756-series modules to create scalable, modular automation racks for centralized control and distributed I/O.
