As part of the ControlLogix system, this controller mounts directly into any slot of a 1756 ControlLogix chassis and operates independently or as part of a multi-controller architecture. It provides reliable execution of user control programs, motion control, and data handling across demanding industrial automation environments.\u003c\/p\u003e\n\u003cp\u003eThis controller features onboard memory for user logic and data storage, supporting seamless integration with RSLogix 5000 programming software. It requires a 1756-BA1 replaceable lithium battery for RAM backup and utilizes standard communication cabling, such as the 1756-CP3 serial cable, for direct controller access and configuration.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard ControlLogix 5550 controller architecture compatible with standard 1756 chassis slots\u003c\/li\u003e\n  \u003cli\u003eSupports multi-tasking, high-speed execution of relay ladder logic, structured text, and function block diagrams\u003c\/li\u003e\n  \u003cli\u003eEquipped with a serial port for programming, configuration, and ASCII communication\u003c\/li\u003e\n  \u003cli\u003eUtilizes the replaceable 1756-BA1 lithium battery for volatile memory backup during power loss\u003c\/li\u003e\n  \u003cli\u003eIntegrates into NetLinx architecture via communication modules for EtherNet\/IP, ControlNet, and DeviceNet connectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDiscrete, process, batch, and drive control systems\u003c\/li\u003e\n  \u003cli\u003eComplex manufacturing assembly lines and packaging machinery\u003c\/li\u003e\n  \u003cli\u003eAutomotive manufacturing plants and material handling systems\u003c\/li\u003e\n  \u003cli\u003eWater and wastewater treatment facility automation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Line\u003c\/td\u003e\n      \u003ctd\u003eControlLogix 5550\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCatalog Number\u003c\/td\u003e\n      \u003ctd\u003e1756-L1M1\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eEnclosure Type\u003c\/td\u003e\n      \u003ctd\u003eOpen-style\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBackplane Current Draw (5V DC)\u003c\/td\u003e\n      \u003ctd\u003e120 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBackplane Current Draw (24V DC)\u003c\/td\u003e\n      \u003ctd\u003e2 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePower Dissipation\u003c\/td\u003e\n      \u003ctd\u003e4.1 W max. at 60 Celsius\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n      \u003ctd\u003e30V (continuous), basic insulation type (communication ports to backplane)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Temperature\u003c\/td\u003e\n      \u003ctd\u003e0 to 60 Celsius (32 to 140 Fahrenheit)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMemory \/ Battery Backup\u003c\/td\u003e\n      \u003ctd\u003e1756-BA1 lithium battery module\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCommunication Port\u003c\/td\u003e\n      \u003ctd\u003eRS-232 serial communication port (compatible with 1756-CP3 cable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eUnited States\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConnections \/ Interfaces\u003c\/h3\u003e\n\u003cp\u003eThe 1756-L1M1 controller features a front-facing RS-232 communication port used primarily for controller configuration, troubleshooting, and serial communication.
