Allen Bradley 1746-A7 Rack SLC 500

Rockwell Allen Bradley 1746-A7 Rack SLC 500 Module

About 1746-A7

The Allen-Bradley 1746-A7 houses the modular processor, communication adapter module, and input and output modules. This chassis is built with 7 slots that is part of the SLC 500 Modular Chassis that provide flexibility in the configuration of systems. In a modular system, each chassis will require its own power supply. The SLC 500 1746-A7 Modular Chassis can be used as a standalone unit in one system or can work with another one or two local chassis. The chassis interconnection cable can be used to build multiple chassis configurations and extend signal lines. This can create a total of 30 I/O slots at maximum. Interconnect chassis vertically with the 1746-C9 cable or 1746-C16 cable that comes in different lengths. Both cables have a rigid, unbending shrink wrap for strain relief when linking modules with one below another. For a horizontal layout, use the 1746-C7 cable. Do not use any other cables for the setup. Longer cables may affect data communication integrity leading to unsafe operation.

SLC 500 System Overview

The Allen-Bradley SLC 500 is a small chassis-based family of programmable controllers, discrete, analog, and specialty I/O, and peripheral devices. The SLC 500 family delivers power and flexibility with a wide range of communication configurations, features, and memory options. The RSLogix 500 ladder logic programming package provides flexible editors, point-and-click I/O configuration, and a powerful database editor, as well as diagnostic and troubleshooting tools to help you save project development time and maximize productivity.
