Product Description

Description

The Allen-Bradley 1747-L511 is an entry-level modular controller processor designed for the SLC 500 system architecture. It is well-suited for discrete small-scale process control, material handling systems, and HVAC equipment control. This processor incorporates a reliable PLC-5 instruction set, providing flexible programming capabilities for standalone machine control or distributed architectures.

Featuring 1K words of battery-backed RAM user memory, the 1747-L511 supports up to 3,040 maximum I/O signals across its supported chassis configuration. It provides essential diagnostic indicators, dependable scan performance, and physical keyswitch operation for security and mode selection (Run, Program, Remote).

Features

  • 1K words of user memory with battery backup support via the 1747-BA module
  • Supports up to 30 I/O chassis module slots across a maximum of 3 chassis
  • Fast program scan time of 1.6 ms per kiloword
  • Equipped with an integral RS-232 communication channel for programming and HMI connection
  • EEPROM memory backup capability for non-volatile program storage
  • Front-panel status indicators for processor fault, run mode, battery status, and communication activity

Applications

  • Small-scale industrial discrete manufacturing
  • HVAC and building automation control panels
  • Material handling and conveyor systems
  • OEM machinery automation

Technical Specifications

Parameter Specification
Manufacturer Allen-Bradley / Rockwell Automation
Exact Model 1747-L511
Product Type SLC 500 Controller Processor
User Memory Capacity 1K words (1,000 instructions)
Backplane Current Draw 350 mA at 5V DC, 105 mA at 24V DC
Program Scan Time 1.6 ms / K (typical)
I/O Capacity Up to 3,040 I/O points

Connections / Interfaces

The 1747-L511 processor includes a single 9-pin D-shell RS-232 port (Channel 0) located on the front panel. This communication port supports DF1 point-to-point, DH-485, Modbus RTU, and ASCII protocols, allowing direct connection to programming terminals, PanelView operator interfaces, or third-party devices. A keyswitch on the front panel enables quick switching between Run, Program, and Remote modes.

Installation Guidelines

Slide the 1747-L511 processor into the leftmost slot (Slot 0) of the primary 1746 I/O chassis, as required by SLC 500 system rules. Ensure power is removed from the backplane before inserting or removing the module. Secure the module using the top and bottom retaining screws, and verify proper battery connection before energizing the system.

Compliance and Certifications

  • UL Listed Industrial Control Equipment
  • cULus Certified for US and Canadian Standards
  • CE Compliant for European Directives
  • C-Tick Marked for Australian Communications Authority
