PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1756-A13/B (Series B). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1756-A13 is a 13-slot chassis designed for ControlLogix modular control systems. It provides physical housing and an electronic communication backplane for system modules. Modules install into any available slot without slot placement restrictions. The backplane manages high-speed data transmission and distributes operating DC voltages to all active modules.
This Series B open-style chassis requires panel mounting in an appropriate industrial enclosure. It operates within a standard temperature range of 0 to 60 degrees Celsius. The unit requires horizontal orientation for proper heat dissipation. It supports standard and redundant ControlLogix power supplies mounted directly onto the chassis framework.
