1756-L55M23 CPU processor

1756-L55M23 CPU processor  

Product Details Introduction

The full name of the model is 1756-L55M23, which belongs to the Rockwell ControlLogix series and is a complete CPU module with pre integrated memory.

The processor is a 100 MHz PowerPC architecture with dual CPU division (main CPU+backplane CPU), resulting in high computational efficiency.

Built in 1.5 MB RAM (user program/data)+1.5 MB non-volatile memory, no additional memory card required.

Boolean instruction execution speed of 0.08 µ s, fast program scanning, suitable for high-speed control scenarios.

Standard RS-232 serial port, supporting protocols such as DF1, ASCII, Modbus RTU, etc.

Supports mainstream industrial buses such as EtherNet/IP, ControlNet, and DeviceNet, and can be used for CIP tag sharing.

Compatible with Studio 5000 (formerly RSLogix 5000), supporting ladder diagram, ST, FBD, SFC programming.

Supports 128 configurable tasks (cycle/event/continuous), with flexible multitasking scheduling.

Maximum I/O capacity: Approximately 128000 digital points, 4000 analog inputs/2000 outputs, with strong scalability.

Compatible with standard ControlLogix racks, supports hot swapping, and is easy to maintain online.

Backboard power supply: 5.1V DC 1.23A, 24V DC 14mA, with a power consumption of approximately 5.7W.

Equipped with 1756-BA1 battery, maintain RAM data and real-time clock after power failure.

Working temperature 0-60 ° C, humidity 5% -95%, no condensation, industrial grade EMC and seismic design.

Support redundant architecture (requiring ControlNet network) to enhance system availability.

Discontinued production, the market mainly focuses on refurbishment/spare parts, suitable for upgrading and maintaining old systems.

1756-L55M23 is an integrated memory version of 1756-L55, which is ready to use and has stable performance. It is a classic controller for medium and large-scale automation systems (automotive, chemical, metallurgical, packaging, water treatment), especially suitable for existing equipment maintenance and renovation projects.
