1745-850 Allen Bradley

Description

Product Name: 1745-850 Allen Braley Input module

Product details:  

The Allen-Bradley 1745-L850 is a processor module belonging to the older but robust PLC-5 family of programmable logic controllers (PLCs). This module is typically used in large-scale industrial control applications.

Note: Information on the specific 1745-850 part number is limited, as this number is often associated with the older SLC 150/100 series (which are obsolete). The most widely recognized and documented high-end processor with a similar number is the 1785-L80B (PLC-5/80B) or other PLC-5/x0 modules. The following details are based on the specifications of the common PLC-5/80 and the broader PLC-5 platform, which is the most likely intended context for a high-end Allen-Bradley processor.

1. Product Details

The 1785-L80B is a high-performance, chassis-based processor designed for complex, high-speed industrial control.

• Product Type: Processor Module (CPU)

• Series: PLC-5 (Programmable Logic Controller)

• Chassis Requirement: It plugs into a 1771 I/O chassis backplane.

• Memory Type: Typically uses battery-backed RAM or Flash memory for program storage.

• Programming Language: Ladder Logic, Structured Text, Function Block Diagram, and Sequential Function Chart (programmed via Rockwell Software’s RSLogix 5).

2. Product Parameters (Specifications)

The specifications for the PLC-5/80 series modules are generally:

3. Product Advantages

The PLC-5 family, including high-end processors like the L80, offered significant advantages in its time, making it a reliable workhorse in many industries.

• High Processing Power: Capable of handling large, complex programs and high I/O counts, making it suitable for major production lines.

• Robust & Reliable: Designed for demanding industrial environments, known for long operational life and durability.

• Extensive Network Capabilities: DH+ and Ethernet (via an added module) support allowed for seamless integration into plant-wide control and monitoring systems.

• Mature Technology: A well-understood and supported platform with a large installed base and a wealth of experienced technicians.

4. Important Considerations (Notes)

While a powerful and reliable system, the PLC-5 platform has some important considerations today:

• Obsolete Status: The PLC-5 platform is considered Legacy by Rockwell Automation. This means new modules are rarely available, and users must rely on surplus markets or repair services.

• Migration: Many companies are actively migrating from PLC-5 to newer platforms like the ControlLogix or CompactLogix series for improved performance, security, and modern connectivity (e.g., Ethernet/IP).

• Software Licensing: Requires older software (RSLogix 5) and potentially older operating systems to run the programming environment effectively.

• Downtime Risk: While reliable, the difficulty in sourcing replacement parts increases the risk of extended downtime when a module fails.

5. Product Applications

The 1785-L80 (and the broader PLC-5 series) was and, in many places, still is widely used across various heavy industrial sectors for its reliability and power.

• Large-Scale Manufacturing: Controlling complex assembly lines, batch processing, and continuous manufacturing.

• Process Control: Applications in oil and gas, refining, and chemical processing where high I/O counts and reliability are critical.

• Water and Wastewater Treatment: Managing pump stations, flow control, and treatment processes.

• Automotive Industry: Controlling body shops, paint shops, and final assembly lines.
