Siemens 6ES7290-6AA30-0XA0 SIMATIC S7-1200 2.0m Extension Cable PLC Accessory

The Siemens 6ES7290-6AA30-0XA0 is a SIMATIC S7-1200 extension cable for a 2-tier module setup, letting SM 12XX signal modules be mounted in a second row beside the CPU instead of end-to-end on the DIN rail. The cable runs 2.0 m, which sets the maximum physical offset between the CPU row and the extended module row on a panel layout.

Technical Specifications

Applications

Connects a second-row SM 12XX signal module bank to an S7-1200 CPU when panel space runs out along the primary DIN-rail row. Rather than extending the module line end-to-end next to the CPU, the 2-tier setup lets additional signal modules sit in a parallel row connected back to the CPU over this 2.0 m link — useful in control panels where the mounting rail is too short for a single-row module count, or where a second tier keeps wiring runs on both rows shorter. This is a passive connection cable: it establishes the backplane bus link only and adds no I/O channels, power, or logic of its own.
