S7 Automation supplies new, obsolete, and hard-to-find Siemens parts for control and automation systems. We support maintenance teams, system integrators, machine builders, and industrial companies that need reliable Siemens spare parts for both current and discontinued equipment.

Many factories still depend on older Siemens SIMATIC S7 systems that are no longer widely available from standard distribution channels. When a PLC module, CPU, power supply, communication processor, or I/O card fails, replacing the complete system can be expensive, time-consuming, and unnecessary.

S7 Automation can help you extend the life of your existing Siemens automation systems by sourcing obsolete and discontinued SIMATIC S7 parts quickly and reliably. This allows you to reduce downtime, avoid urgent retrofits, and keep production running while planning future upgrades on your own schedule.

We can help you source:

SIMATIC S7 CPUs
Digital and analog I/O modules
Power supplies
Communication processors
Interface modules
HMI panels
Cables and accessories
New, obsolete, and refurbished Siemens automation parts

With 4 warehouses and more than 132,000 parts in stock, we are able to support urgent breakdowns, planned maintenance, and spare parts inventory requirements.

Every part supplied by S7 Automation includes a 2-year warranty, giving you confidence when purchasing new, obsolete, or refurbished Siemens automation parts.
