Siemens 6ES5922-3UA11 Programmable Logic Controller Module

Siemens 6ES5922-3UA11 CPU 922 central controller module for SIMATIC S5 CC 135U/155U systems. The CPU 922R processor serves as the central processing unit within the S5 Central Controller family, executing PLC programs and coordinating I/O in legacy automation setups. This module is designed for CC 135U/155U configurations and fits the standard S5 central controller form factor. Verified specifications include a CPU 922R processor and compatibility with the 135U/155U CC systems; dimensions are 210 mm high, 260 mm long, and 30 mm wide, with a weight of about 0.4 kg. Lifecycle notes indicate the product lifecycle ended on January 15, 2010, and distributor listings show it as not RoHS-compliant. Typical applications for this module are maintenance and retrofits of older Siemens S5 automation networks where a CPU 922R is required to sustain control tasks in CC135U/155U environments. The part is listed under Siemens 6ES5922-3UA11, with common market-facing numbering such as 6ES59223UA11, reflecting its place in the S5-135U/155U Central Controller lineup. End-of-life status means replacement options may be limited, so this module remains relevant for repairs and ongoing operation of historic equipment.
