1756-L55M24 Functional Description    

The Allen-Bradley 1756-L55M24 is a versatile processor module within the ControlLogix platform, designed to deliver a wide range of control functions, including safety, motion, discrete, and drive control, along with enhanced I/O capabilities. The modular architecture of the ControlLogix system allows for efficient design and modification. Its compact chassis houses the 1756-L55M24 processor module (also referred to as the controller), and various I/O modules, with flexible communication options through additional communication modules such as Ethernet, DeviceNet, ControlNet, DH+, SynchLink, and Remote I/O.

The Rockwell 1756-L55M24 controller can be installed in any slot of the system chassis and supports hot swapping—meaning the controller can be installed or removed without powering down the system, but caution is advised in hazardous environments to avoid potential risks like explosions. In such cases, the system should be powered off before inserting or removing the controller. This processor boasts 3.5 MB of non-volatile user memory, eliminating the need for a battery, and features an integrated RS-232 serial port for communication.

Supporting multiple programming languages, including relay ladder, SFC, function block, and structured text, the 1756-L55M24 Powerful Processor Module ensures flexible control and automation. It also requires specific programming cables, namely the 1756-CP3 and 1747-CP3 serial cables. The system draws 1.25 Amps at 5.1 V DC and dissipates 5.7 W of power, generating 19.4 BTU per hour of thermal dissipation. Operating within a temperature range of 0 to 60°C and relative humidity levels of 5 to 95%, the 1756-L55M24 GUARDLOGIX 5562S PROCESSOR offers robust performance across various industrial environments.
