Structure
An electrical base module consists of a distributor module (backplane bus) and a function module. Both modules
are contacted via a 14-pole board-to-board plug. The bus signals on the distributor module are protected from
interference by a shield support.

The function module can be disconnected and connected during operation the same as the electronic modules of
the ET200S. If several modules are replaced, the modules must be disconnected and reconnected in succession
(5-23 ET200S EWA4NEB 780602401-06). To ensure the switching process, 24 V is applied briefly to the valve
when connected. The power on the valve is reduced to one quarter after approx. 120 ms.
