S5 Product Life Cycle
Please note that there is already an announcement regarding end of product life cycle for S5 products. Spare parts can still be obtained until September 30, 2020
, subject to availability and possibly only with the exchange.
The S5 Product line has been around since 1979 and has been serving a lot of customers for the past years since then. With the phase-out of this product line, it will become increasingly complex and expensive to maintain these control systems.
