Siemens 6ES7290-6AA20-0XA0 Programmable Logic Controller

Siemens 6ES7290-6AA20-0XA0 is an extension cable for the EM of the SIMATIC S7-200 CPU 22X, with a length of 0.8 meters. It is designed to connect the expansion module (EM) interface of the CPU 22X to compatible EM devices in SIMATIC S7-200 systems. The part number denotes the 0.8-meter variant within the S7-200 extension cable family. This cable provides the necessary physical link between the CPU and EM hardware in installations that require extra reach. Compatible systems include the SIMATIC S7-200 family featuring CPU 22X and EM modules that use the 6ES7290 series connector interface. Common applications involve small automation projects where S7-200 controllers manage expansion modules for additional I/O or peripheral integration. The 0.8 m length is a defining specification that informs routing and enclosure planning.
