Allen-Bradley 1756-L62 ControlLogix Processor

The Allen-Bradley 1756-L62 ControlLogix Processor (Logix5562) is a ControlLogix central controller with 4 MB of on-board user memory, designed to run sizable automation programs in standard ControlLogix racks. It provides a compact yet powerful processing solution for coordinating a wide range of I/O across the backplane, with compatibility for RSLogix 5000 and Studio 5000 development environments and an on-board RS-232 serial port for programming and diagnostics. The 4 MB of user memory supports larger ladder logic or structured text programs and data tables, making it suitable for medium-to-high complexity control tasks in process, material handling, packaging, or machine automation applications. It is part of the Logix5562 family, a line of controllers known for integrated processing within a Rockwell Automation ecosystem and broad module compatibility with 1756 I/O and the standard ControlLogix backplane. Typical deployments place the 1756-L62 in a ControlLogix chassis with compatible 1756 I/O and communication modules, running RSLogix 5000 or Studio 5000 software to develop and maintain logic. Electrical characteristics include a 4 MB user memory and a modest power draw, with current draw listed as approximately 14 mA at 24 VDC.
