Programmable Logic Controllers
SLC 500 System
Overview
Power and Flexibility for a Complete Control Solution
The Allen-Bradley SLC 500 is a small, chassis-based, modular family of programmable controllers and I/O. With its multiple processor choices, numerous power supply options and extensive I/O capacity, the SLC 500 allows you to create a system specifically designed for your application.
As one of the first full-featured small controllers on the market, it remains the gold standard in small logic controllers more than a decade after its introduction.
Right For Today. Ready For Tomorrow.
SLC 500 controllers control hundreds of thousands of processes around the world — everything from amusement park rides to pharmaceutical processing.- 1.6M processors and 12M, I/O modules installed worldwide
- Used by over 75% of companies comprising the Dow Jones Industrial Average (DJIA)
- Large choice of I/O available from Rockwell Automation and third party companies, making these products appropriate for almost any application
- Over 100,000 customers trained in the U.S. alone, making this product one of the most understood of its type
- Proven Reliability. An example is the addition of 1747-BSN Back-Up Scanner, which has grown application base to even more critical areas
- Step Forward program ensures customer can upgrade to latest technology
New Developments Now Available
- MODBUS RTU Master capability: Provides increased compatibility with SCADA applications and 3rd party devices. Compatible with other RA Modbus-compatible products including MicroLogix controllers and PowerFlex drives.
- Improved PID instruction: Provides better accuracy in the PID instruction with the implementation of rational approximation feature.
- 1747-DPS2 RS-232/DF1 Configurable Port Splitter: Allows a single RS-232/DF1 port on a Rockwell Automation controller (e.g. SLC 500, MicroLogix, PLC-5, ControlLogix, CompactLogix) to be expanded (or split) into two ports for communication with a network and an HMI or Programming Station.
A Solid Investment. Today. Tomorrow.
- Excellent quality now and in the future
- Continued support for an enormous installed base
- On-going engineering investment
- Customer advance warning long before any products are no longer available for sale
We are committed to selling & supporting SLCs into the next decade!
Management Statement
Dear Customer,
Rockwell Automation appreciates your investment in the Allen-Bradley SLC 500, and we will continue to protect that investment. We offer a complete range of SLC 500 products for sale to service a wide variety of applications. And we continue to invest in the SLC 500 architecture. Our most recent additions include Modbus RTU Master Protocol capability for SLC 5/03, 5/04 and 5/05, a new SLC 5/03 processor with increased (32K) memory, and the new 1747-DPS2 Configurable Port Splitter.
We plan to actively market and manufacture the SLC 500 product line well into the next decade. This line will continue to service those small to mid-range PLC applications where high performance and a wide variety of communication networks and I/O structures are important.
Allen-Bradley plans to continue to offer hardware/firmware upgrades and repair of SLC 500 Family products. Protecting our customers’ investment is a significant reason we have an installed base over 1.6 million CPU and over 12 million 1746 I/O installations world-wide. Furthermore, it is our practice to support products for seven years from the date they are removed from general sale, pending availability of components.
To give you some idea of our commitment to our customers, the 1772 Series PLC-2 family, which was introduced in 1979, was removed from sale in 2002. That is a product life in excess of twenty years. While we cannot predict component availability and market forces for the SLC 500 that would allow us to do the same, we are committed to the sale and support of the SLC 500 family for the foreseeable future.
I hope that this brief correspondence will give you some idea of Allen-Bradley’s commitment to providing a quality automation product and commitment to the SLC 500 product line.
