BULLETIN 1746 AND 1747
Powerful, yet affordable - SLC 500 programmable controllers provide excellent
value with extensive capabilities to address a broad range of applications
material handling, HVAC control, high speed assembly operations, small process
control, simple motion control, and SCADA.
Modularity - Modular processes, power supplies, I/O, memory options, and
communication interfaces allow for a configurable and expandable system.
Configure your system for the number of I/O, the amount of memory, and the
communication networks needed. Later, you can expand the system by adding
memory, or communication interfaces.
Advanced instruction set - Includes indirect addressing, high level math
capability, and a compute instruction.
Communication network versatility - Choose from on-board Ethernet, DH+, or
DH-485, as well as options for ControlNet, DeviceNet, or Remote I/O
Broad selection of I/O - Select from over 60 modules to control discrete, analog,
and temperature signals. Third-party specialty modules are also available from
Encompass partners to customize control solutions for your application needs.
Industrially hardened product - Designed to withstand the vibrations, thermal
extremes, and electrical noise associated with harsh industrial environments.
Windows programming software - RSLogix 500 programming software
maximizes productivity by simplifying program development and

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.

Local Systems
At minimum, a modular hardware SLC 500 control system consists of a
module and I/O modules in a single 1746 chassis with a power supply.
Power Supply
I/O Modules
You can configure a system with one, two, or three local chassis, for a maximum
of 30 local I/O or communication modules. You connect multiple local chassis
together with chassis interconnect cables to extend the backplane signal lines from
one chassis to another.
