Allen-Bradley 1756-L55 Logix5555 Processor Module

Description

The Allen-Bradley 1756-L55 Logix5555 Processor Module is a programmable logic controller (PLC) module designed for industrial automation systems. Featuring a modular design, it supports flexible configuration and scalable input/output channel counts to adapt to varying system requirements. Built for industrial-grade environments, it delivers high reliability with strong anti-interference capabilities and long-term stability, meeting IEC 60068 standards for temperature, humidity, vibration, and shock resistance.

Key technical specifications include a Logix5555 processor type, 1.5MB memory, and a 24V DC power supply, with an operating temperature range of -40 degrees Celsius to 70 degrees Celsius. It measures 86mm x 101mm x 113mm and weighs 0.4kg. Equipped with EtherNet/IP and ControlNet communication interfaces, it enables seamless integration into complex industrial networks. The module does not include user memory but comes with a 1756-BA1 battery, and supports configuration and debugging via Rockwell Automation’s dedicated software. It serves as a core component for input/output control in manufacturing and industrial processes, with optional support for redundant controller architecture that enables shock-free switchover between main and backup units for uninterrupted operation.
