Obsolete S7-200 Parts Sourcing

Discontinued platform parts, sourced globally and tested before shipping.

Overview

The SIMATIC S7-200 was the world's highest-volume small PLC — and Siemens discontinued it in 2017. Every CPU, module and cable in circulation today is sourced stock. TGK Parts maintains an active sourcing line for obsolete S7-200 parts: CPUs, EM expansion modules, CP communications processors, PPI/DP cables and accessories.

Send us the MPN or a nameplate photo — we reply within 12 hours with availability, condition grade and price. Program transfer and functional testing available before shipping.
