Allen-Bradley SLC 500 System

Allen-Bradley SLC System

RockWell Allen-Bradley 1747 SLC™ 500 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.

Features

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

Chassis

Allen-Bradley SLC PLC System 1746 SLC™ 500 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™ 500 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™ 500 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.

Controllers

Allen-Bradley SLC PLC System 1747 SLC™ 500 controllers provide a range of choices in memory, I/O capacity, instruction set,

SLC 500 I/O Modules

SLC I/O

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.
