Established in 2011, we have built a strong reputation for delivering reliable automation solutions to a global clientele across North America, Europe, Asia, and beyond. This processor represents a cornerstone of the proven SLC 500 platform, designed to deliver robust and dependable control for a wide array of industrial applications. We understand that system uptime and stability are paramount for our B2B clients, and this unit is engineered to meet those critical demands.
The Allen-Bradley 1747-L524 is a mid-range processor for the SLC 500 modular controller system. It serves as the central intelligence for controlling machinery, processes, and discrete manufacturing tasks. Its design focuses on providing a cost-effective yet powerful control solution for applications that require more than basic relay logic but may not need the extensive capabilities of larger ControlLogix systems.
Core Technical Specifications and Features:
- Processor Performance: The SLC 5/02 processor executes ladder logic instructions efficiently, handling complex control sequences, timing, counting, and data manipulation tasks essential for automated systems.
- Memory Configuration: This processor is equipped with 8K words of user memory. This memory is used for storing the ladder logic program, data tables for I/O status, timer/counter values, and integer files, providing ample space for moderately complex control programs.
- Integrated Communication: A key feature is its built-in communication capability. It includes a DH-485 network port and an RS-232 (DF1 protocol) port. The DH-485 network allows for peer-to-peer communication with other SLC processors, PanelView terminals, and programming devices, facilitating distributed control systems. The RS-232 port is used for direct programming, uploading/downloading programs, and system troubleshooting.
- System Scalability: The 1747-L524 can be configured in a local chassis with a mix of digital and analog I/O modules. It supports a total addressing capacity of up to 256 digital I/O points (depending on chassis and module configuration), allowing the system to grow with your application needs.
- Robust Industrial Design: Built to withstand harsh industrial environments, it operates reliably in conditions with electrical noise, vibration, and temperature variations typical of factory floors.
- Programming Software: It is programmed using Rockwell Automation's RSLogix 500 software, an industry-standard environment that simplifies development, debugging, and documentation of control logic.

Frequently Asked Questions (FAQ):
Q1: What is the main difference between the SLC 5/02 (1747-L524) and the SLC 5/03 or 5/04 processors?
A1: The primary differences lie in communication and memory. The 5/02 uses DH-485/RS-232, while the 5/03 adds an RS-232/RS-485 port and supports more protocols. The 5/04 features a built-in DH+ port for higher-speed network communication. The 5/02 is a solid choice for standalone or small networked applications where DH-485 is sufficient.
Q2: Can I use RSLogix 500 software to program the 1747-L524?
A2: Yes, absolutely. The Allen-Bradley 1747-L524 SLC 5/02 processor is programmed using Rockwell Automation's RSLogix 500 programming software. You will need the appropriate cables (like a 1747-CP3) to connect your computer to the processor's RS-232 port.
Q3: What is the maximum number of I/O modules I can connect to this processor?
A3: The maximum I/O capacity is determined by the chassis and addressing. A typical local chassis configuration can support several modules. The processor itself can address up to 256 digital I/O points. The exact module count depends on the mix of digital, analog, and special function modules used, as each has a different point consumption.
Q4: Does the 1747-L524 have battery-backed memory?
A4: The processor itself does not contain a battery. To retain the user program and data table contents in the event of a power loss, you must install an optional memory module (like a 1747-M1 or M2) in the designated slot on the processor. This module contains a battery for retention.
Q5: Is this processor still manufactured by Allen-Bradley, and is it a good choice for new systems?
A5: The SLC 500 series has been declared legacy by Rockwell Automation, meaning it is not actively promoted for new designs. However, it remains widely available on the market and is an excellent, cost-effective choice for modernizing existing SLC-based systems, for spare part replacements, or for new projects where its capabilities are perfectly matched and long-term lifecycle support is understood.
Q6: What kind of power supply does the processor need?
A6: The processor module itself receives power from the backplane of the SLC 500 chassis (e.g., 1746-A4, A7, A10, A13). You must install a compatible 1746 power supply module (such as P1, P2, P3, or P4) in the chassis's left-most slot to provide this backplane power.
Q7: Can it communicate with modern Ethernet-based devices?
A7: Not directly. The 1747-L524 does not have a native Ethernet port. To connect it to an Ethernet network, you would need a communication gateway or converter module (such as a 1761-NET-ENI) that can bridge between the processor's DH-485 or DF1 serial network and Ethernet/IP.
