Allen-Bradley 1747-L541 SLC 5/04 Processor

Allen-Bradley 1747-L541 SLC 5/04 Programmable Controller

• Brand & Model: This is an Allen-Bradley controller, specifically the 1747-L541 model from the SLC 5/04 product line.
• Memory & Processing: It features 16 KB (16,000 words) of battery-backed user memory. The processor offers a fast 0.9 ms/K program scan time and a 0.225 ms I/O scan time.
• High-Speed Communication: Built-in Data Highway Plus (DH+) and 9-pin RS-232 ports enable extended messaging and network flexibility. DH+ supports high-speed, multi-drop communication.
• I/O System Capacity: The controller supports up to 4096 discrete inputs and 4096 discrete outputs. It can also manage 480 analog I/O points for process control tasks.
• Interrupt & Timing: It includes a 1 ms Selectable Timed Interrupt (STI) and a rapid 0.5 ms Discrete Input Interrupt (DII) for precise event handling.
• Hardware Configuration: You can configure up to 3 local I/O chassis with this processor. The system supports a maximum of 30 module slots for flexible expansion.
• Power Requirements: The 1747-L541 requires 1 Amp at 5V DC and 200 mA at 24V DC from the backplane for proper operation.
• Backup & Diagnostics: It uses a 1747-BA battery for backup and a 1747-M13 Flash memory module. Front-panel LEDs for RUN, FLT, DH+, and RS-232 provide clear status indicators.

Advanced Features & Communication

• The 1747-L541 supports advanced math instructions and indirect addressing. It enables remote I/O and DeviceNet pass-through for distributed system architectures.
• The RS-232 port is configurable for DF1, DH-485, ASCII, and Modbus RTU protocols. This allows connections to radios, modems, and other serial devices.
• You can connect the serial port to a 1761-NET-AIC converter. This creates a multi-drop network for connecting multiple devices easily.
• A 3-position key switch on the front panel selects Run, Remote, or Program modes. This provides physical control over the processor's operation.
• The controller operates reliably in a 0 to 60°C temperature range. It carries UL, CE, and C-Tick marks for compliance with international standards.
