Allen-Bradley 1764-LSP MicroLogix 1500 Standard Processor Unit

Product Overview

The Allen-Bradley 1764-LSP functions as the central intelligence for the MicroLogix 1500 controller system. This standard processor module executes complex logic commands, manages I/O data, and coordinates communication across the automation network. It features 7.65K user words of memory and supports user-configurable program and data storage to meet specific application requirements. We supply this unit in 100% Brand New condition, providing a definitive solution for maintaining or expanding legacy MicroLogix 1500 installations with original factory hardware.

Engineering Advantages

The 1764-LSP optimizes control system performance through its modular architecture and flexible memory management:

• Modular Maintenance Strategy: The processor separates from the base unit (power supply and I/O). This design allows maintenance teams to replace the processor without disturbing field wiring, significantly reducing Mean Time To Repair (MTTR) and preventing wiring errors.

• Flexible Memory Allocation: Users configure the 7.65K memory based on specific project needs. This flexibility allows for larger data tables or extensive ladder logic instructions, adapting to varied industrial tasks from simple relay replacement to complex machine control.

• Efficient Power Profile: The module draws only 300 mA at 5V DC from the base unit. This low power consumption minimizes heat generation within the control cabinet, extending the lifespan of the processor and adjacent electronic components.

• Seamless Legacy Integration: As a Brand New original component, the 1764-LSP provides a direct "drop-in" replacement for failed units. It maintains full compatibility with existing RSLogix 500 programming and 1764-series base units, eliminating the need for costly system re-engineering or software migration.

FAQs

• Does the 1764-LSP require a base unit to function?

  Yes. The 1764-LSP is a processor module only. You must plug it into a MicroLogix 1500 base unit (such as a 1764-24AWA or 1764-28BXB) which provides the power supply, I/O terminals, and the communication port.

• Is this a Brand New original product or a refurbished unit?

  We guarantee this 1764-LSP is 100% Brand New original stock. While the manufacturer discontinued this series in 2017, our new-in-box units ensure the internal battery and capacitors possess their full original service life, unlike used or refurbished alternatives.

• Can I use my existing RSLogix 500 software to program this module?

  Yes. The 1764-LSP utilizes standard RSLogix 500 programming software. You can download your existing .RSS files directly to this new processor to restore machine operation immediately.

• What precautions should I take during installation?

  Ensure you power down the base unit before inserting or removing the 1764-LSP processor. Align the module pins carefully with the base connector to prevent physical damage during the mating process.
