Siemens 6es5 095-8ma04 Programmable Logic Controller

Siemens 6ES5 095-8MA04 is a SIMATIC S5-95U Compact Unit, the compact CPU module at the heart of Siemens' classic SIMATIC S5 PLC family used for legacy industrial automation tasks. The MA04 suffix denotes a base variant with no additional interface options, aligning with the MA designation for S5-95U parts that ship without extra interface hardware. This device is typically programmed with STEP 5 and provides the essential control functions for sequencing, timing, and I/O control in older machinery, operating within the S5-95U system architecture. Catalog references commonly list this variant as 6ES50958MA04, situating it squarely within the S5-95U family for replacement parts and maintenance of vintage automation lines.
