Allen-Bradley SLC System

RockWell Allen-Bradley 1747 SLC™ ۵۰۰ PLC is a chassis-based, modular family of controllers and I/O. With multiple processor choices, numerous power supply options and extensive I/O capacity, the SLC 500 family provides a powerful solution for mid-range stand-alone or distributed industrial control. As one of the first full-featured small controllers on the market, it remains the gold standard in logic controllers more than a decade after its introduction.


  • Up to 64 K words of configurable data and program memory
  • Control up to 4096 input and 4096 output signals
  • Configure up to three local chassis, with 30 local I/O or communication modules maximum
  • Monitor and control remotely located I/O across ControlNet™, DeviceNet™, and Universal Remote I/O links (requires I/O scanner module)
  • Built-in ports for EtherNet/IP™, DH+, DH-485, or RS-232 communication
  • Available communication modules provide additional communication options
  • Specialty modules support simple motion control applications
  • Continued support and on-going engineering investment for a large installed base


  • ۱۷۴۷ SLC™ ۵۰۰ Controllers
  • ۱۷۴۶ SLC I/O
  • ۱۷۴۶ Chassis
  • ۱۷۴۷ Communication Interface Modules
  • ۱۷۴۶ Power Supplies


  • UL, C-UL, CE, C-Tick

Certifications apply when product is marked. See our Product Certification site for Declarations of Conformity, certificates and other certification details.


Allen-Bradley SLC PLC System 1746 SLC™ ۵۰۰ Power Supplies provide power to installed controllers or adapters and I/O modules in an SLC chassis. Seven power supplies support a range of AC and DC input voltages.

Allen-Bradley SLC™ ۵۰۰ system requires a chassis to contain the various modules. Chassis are available in sizes of 4, 7, 10, and 13 module slots. The backplane provides a communication path between the I/O modules and either the controller or the I/O adapter module.

Communication Interfaces

Allen-Bradley SLC PLC System 1747 SLC™ ۵۰۰ Communication Interface Modules let you add another communication port to the SLC 500 controller. This adds network capability beyond the available on-board ports. Some modules provide an interface between a port on the controller and another communication link with a different protocol. Other modules communicate with the SLC processor over the system backplane.


Allen-Bradley SLC PLC System 1747 SLC™ ۵۰۰ controllers provide a range of choices in memory, I/O capacity, instruction set,



and communication ports to let you tailor a control system to your exact application requirements. Our controllers have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.SLC 500 Controller Comparison:

SLC 500 I/O Modules


Allen-Bradley SLC PLC System 1746 SLC™ I/O provides a full range of digital, analog, and specialty I/O for a wide variety of applications. You can use the I/O modules in a local I/O chassis of an SLC 500 controller. Or, use an I/O communication adapter module to place I/O in a chassis at a location remote from the controller.
