SLC500 System

Power and Flexibility for a Complete Control Solution
The Allen-Bradley SLC 500 is Rockwell Automation's small, chassis-based, modular family of programmable controllers and I/O. The SLC's smaller size means that you can use an SLC in applications where you can't afford the size and overhead of a traditional, full-size PLC. With its multiple processor choices, numerous power supply options and extensive I/O capacity, the modular SLC 500 controller allows you to create a system specifically designed for your application.

The SLC 500 was one of the first full-featured small controllers on the market, and it remains the gold standard in small logic controllers more than a decade after its introduction. In fact, the SLC 500 provides cost-effective, reliable control in hundreds of thousands of applications around the world -- everything from amusement park rides to pharmaceutical and food processes.

Choice of Controllers

The SLC 500 line offers a range of choices in memory, I/O capacity, instruction set, and communication ports to allow you to tailor a control system to your exact application requirements. These products have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.

SLC 5/01 processors let you configure modular controllers of up to 960 I/O and a 1K- or 4K-instruction memory capacity.
SLC 5/02 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs nominally and a 4K-instruction memory. By installing an optional scanner module into one of the 30 I/O module slots, you can add Remote I/O or DeviceNet I/O to the system. They offer 19 additional instructions, including a message instruction for initiating peer-to peer communication.
SLC 5/03 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of 8K or 16K words. In addition to the features of the SLC 5/02, they have a second built-in communication port — an RS-232-C port that can be configured for ASCII or DF1 protocol, and can be configured for connection to a 1761-NET-AIC converter to provide access to a DH-485 network.
SLC 5/03 processors provide bit-instruction execution times of 0.44ms and an overall system throughput of up to 10 times faster than competitive processors. Additional capabilities include: floating-point math, online programming and run-time editing, flash memory upgrades, built-in key-switch, and a built-in real-time clock and calendar.
SLC 5/04 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of either 16K, 32K, or 64K words. They have all the features of the SLC 5/03 processors, plus a faster communication port and shorter execution times (bit-instruction execution times of 0.37ms). Instead of a DH-485 port, the SLC 5/04 has a built-in DH+ port for communication with other SLC 5/04 and PLC processors, operator interfaces, and programming terminals. Communication via the DH+ network is three times faster than DH-485 communication.
SLC 5/05 processors provide high bandwidth networking for standards-based distributed programmable controller systems. They have all of the features of the SLC 5/04 processors, but instead of a DH+ port they provide a 10BASE-T 10/100 Mbps Ethernet connectivity to the popular SLC 500 family. Through Ethernet networks, SLC 5/05 processors can communicate plant-floor data in data acquisition, supervisory control, program management, statistical quality control, maintenance management, production scheduling, and material tracking applications.
