Siemens 6ES7290-6AA30-0XA0 SIMATIC S7‑1200, Extension Cable, 2‑Tier SM 12XX, 2.0 m Original Brand New

Overview

The Siemens 6ES7290-6AA30-0XA0 is a crucial accessory for expanding the capabilities of your SIMATIC S7-1200 programmable logic controller (PLC) system. This specialized extension cable is engineered to facilitate a 2-tier (two-row) physical arrangement of the S7-1200’s Signal Modules (SM 12XX), such as digital or analog I/O modules. With a length of 2.0 meters (2m), it provides the necessary distance and flexibility to connect modules in larger, more complex control cabinet layouts while maintaining high-traffic, reliable signal integrity.

Benefit

• Optimized Space Utilization: Allows you to install Signal Modules (SM) in a secondary row, effectively doubling the density of I/O within the same control cabinet width.

• Reliable Performance: Designed specifically for the S7-1200 system, ensuring stable and reliable communication between the CPU and remote I/O modules.

• Installation Flexibility: The 2.0m length provides sufficient reach for routing the connection cleanly and efficiently in medium to large industrial enclosures.

• Reduced Wiring Complexity: Provides a standardized, high-speed connection alternative to extensive point-to-point wiring, simplifying installation and maintenance.

Function and Application

The primary function of the 6ES7290-6AA30-0XA0 cable is to connect a SIMATIC S7-1200 CPU or a Signal Module (SM) in the first row to a Signal Module in a second, offset row. This setup is typical in applications where the number of required I/O points exceeds the capacity of a single-row configuration or when optimizing cabinet depth is necessary.

Typical Applications:

• Large-scale Machine Control: Used in complex machinery requiring numerous digital and analog I/O points where a compact, multi-row setup is mandatory.

• Cabinet Space Optimization: Ideal for control panels with limited mounting rail space that require high module density.

• System Upgrades: Facilitates the non-disruptive addition of I/O capacity to an existing S7-1200 installation.
