Product Overview
The Allen‑Bradley 1756‑A13 is a standard 13‑slot main chassis for ControlLogix PAC system. The integrated backplane distributes power and high‑speed parallel communication signal among CPU, digital / analog I/O, communication modules. Modules can be inserted into any slot without fixed position restriction. Empty slots must be filled with 1756‑N2 slot filler to guarantee airflow and EMC performance. It solves pain‑points for medium‑large ControlLogix projects: insufficient slot quantity for mixed I/O and multi‑communication modules. Automation engineers, panel builders and maintenance technicians benefit from flexible slot allocation, full compatibility with 1756 series modules, drop‑in spare‑part replacement for existing ControlLogix racks。
