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.
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

Chassis
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.
Controllers
Allen-Bradley SLC PLC System 1747 SLC™ ۵۰۰ 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.
