The Allen-Bradley SLC 500 System is a modular, small chassis-based class of programmable controllers integrating discrete, analog, and specialty I/O and peripheral devices in stand-alone electronics cabinets.
The System has become the choice of manufacturing engineers worldwide because it is the industry standard for reliability and cost effectiveness. Consider these features that make the SLC 500 System the option you should consider:
Creating a SLC 500 System may seem to be a daunting task at first, but it is really a very straightforward proposition. The first step is to examine the manufacturing blueprints, and all related machine and electrical functions requiring an input /output. Plot the entire operation in a spreadsheet to determine the exact number of I/O points that will be required as well as the amount of memory needed to complete the operations. Once you have determined the number of I/O points, and all specialty applications, such as temperature controllers, you are ready to select the various elements of the SLC 500. Here are some ideas on selecting the appropriate hardware, and accompanying tables identifying the various components and their capabilities.
To create an SLC 500 System there are a few basic steps to take. The following checklist will guide you through the various steps required:
Well, there you have it: a basic tutorial to make you familiar with and help you to configure your SLC 500 system. Following these simple steps will assist you in creating a system that will handle all aspects of your requirements. Furthermore, the Allen-Bradley SLC 500 is one of the most reliable and cost-effective options available in the industrial marketplace, and has been for many years. Go ahead. Design your system using the SLC 500. You'll be glad you did!
Allen-Bradley offers both discrete (digital) and analog Input and Output modules of various capabilities. The digital Input/Output modules feature a discrete signal that is either on or off, such as the input of limit switches or the output signal to a relay. Conversely, analog Input/Output modules convert voltage or current to point-in-time values via the processor, such as the input received by a thermocouple or the output signal of a pressure regulator. Virtually all SLC 500 Systems will incorporate the use of both discrete and analog Input and Output modules.
The SLC 500 System delineates between the various discrete modules by sorting them into two categories: Sinking and Sourcing. As an engineer designing your own system it will help you to understand the difference between these two options. Here is the definition as given by Allen-Bradley:
"Sinking and Sourcing are terms used to describe a current signal flow relationship between field input and output devices in a control system and their power supply.
The following tables will help you to compare the Discrete Input/Output modules available in the Allen-Bradley SLC 500 System as well as the Analog Input/Output modules:
You will need to ascertain what your communication requirements are going to be, which will help you to select the proper communication modules for your system. Processors used in the SLC 500 PLC system communicate across the 1746 backplane, contained in the chassis, to the various Input/Output modules in the system. The different processors have a variety of communication ports on board for communication with other processors and computers. These varied communication ports will be part of the criteria you will use in selecting the right processors for your system. Every processor in the SLC 500 series has one or two built-in ports for direct communication with EtherNet/IP, DH+, DH-485, or RS-232 (DFI, ASCII, or DH-485 protocols).
Additionally, separate modules can be incorporated into the system's design to provide other communication ports within the system. Modules for ControlNet and Universal Remote Input/Output links are an option, as well as I/O adapter modules to interface I/O modules with scanner ports in remote locations. The Communication Modules available are denoted in the following table.
Selecting a processor is the next step in designing your system. After taking all the steps above, it is possible to determine your processor needs. You will choose the processor needed based on memory, number of Input/Output modules, speed, communications, and programming requirements of your system. Here are the basic features of the SLC 500 Processors by type of processor:
Available in four different sizes, the SLC 500 chassis offers maximum flexibility as you configure your system. The chassis come in 4-slot, 7-slot, 10-slot, and 13-slot options to allow you to design the perfect system for your application. The chassis accepts the SLC 500 processor module or the SLC 500 adapter module and the various Input/Output modules. Every chassis will need its own power supply, which installs on the left side of the chassis. You can connect a maximum of three chassis with the available chassis interconnect cables. The following table delineates the chassis and cable options available for the SLC 500 system.
Each chassis in the SLC 500 system requires its own power supply. You will need to analyze your system requirements thoroughly to ascertain the power supply requirements for each chassis. Overloading a power supply can result in system shutdown and/or premature failure of the power supply or other system components. This is not the place to underrate system needs. As you calculate your system's power needs, don't forget to include possible future enhancements to the system. When configuring your system, it is always safer to provide excess power than to be borderline on your system's requirements.
The SLC 500 system has three AC and four DC power supply options. Mounting on the left side of the chassis, the power supply requires just two screws. The AC options are 120/240 volt selectable. All the power supplies have an LED indicating it is working normally. Each power supply can withstand brief power losses, which enables the system to continue normal functioning. All SLC 500 power supplies operate at 0 to 60° C (32 to 140° f) and use #14 AWG wiring. The power supply options for the SLC 500 are specified in the following table.
The SLC 500 system uses RSLogix 500 ladder logic programming.

Allen Bradley SLC 500 I/O Modules
The SLC 500 System delineates between the various discrete modules by sorting them into two categories: Sinking and Sourcing. As an engineer designing your own system it will help you to understand the difference between these two options. Here is the definition as given by Allen-Bradley:
"Sinking and Sourcing are terms used to describe a current signal flow relationship between field input and output devices in a control system and their power supply.
- Field devices connected to the positive side (+V) of the field power supply are sourcing field devices.
- Field devices connected to the negative side (DC Common) of the field power supply are called sinking field devices.
- Sourcing I/O circuits supply (source) current to the sinking field devices.
- Sinking I/O circuits receive (sink) current from sourcing field devices.
