Allen-Bradley 1775-L4 Programmable Controller Processor Module

The Allen-Bradley 1775-L4 is a programmable controller processor module designed for the PLC-3/10 series. As the ‘brain’ of the system, it handles program execution and memory management functions. Despite its single-slot design, it provides a powerful set of features for industrial applications.

Key Features and Benefits

• Single-slot design: Optimizes space within the controller chassis.
• High-speed program scan: Ensures quick response and efficient operation.
• Over 70 programming instructions: Offers flexibility for complex control logic.
• Completely flexible data table: Enhances memory efficiency.
• Multiple contexts: Allows rapid switching between programs.
• Real-time clock and calendar: Supports time-based control and scheduling.
• On-board diagnostics: Assists in troubleshooting and maintenance.
• Integer, floating-point, and double-precision math: Handles a range of calculations.
• Programmable fault response: Customizes error handling.

Technical Specifications

While specific specifications may vary, general characteristics include:

• Memory: Typically includes program, data, and system memory.
• I/O: The 1775-L4 communicates with I/O modules rather than directly handling I/O.
• Power requirements: Varies based on system configuration, as specified in the documentation.
• Environmental conditions: Operates within a specified temperature and humidity range.

Applications

The Allen-Bradley 1775-L4 suits various industrial applications, such as:

• Manufacturing: Controls production lines, assembly processes, and packaging systems.
• Material handling: Manages conveyor systems, robotic arms, and storage/retrieval systems.
• Process control: Regulates temperature, pressure, flow rate, and other variables.
• Machine control: Operates machine tools, CNC machines, and automated equipment.
