ESCRIPTION
Basic electronic module ME02 / 2-fold monostable
Construction
An electric base module consists of a distribution module (backplane bus) and a function module.
The two modules are connected by a 14-pin board-to-board plug.
Possible combinations with valve types

Function display of LEDs
reed / green LED
yellow LED
Display of the switching position
no function
Display of network status (only 2nd valve position)
Display of module status (only 1st valve position)
As with the electronic module of the point I/O system, the function module can be installed and
removed during operation. In order to ensure the switching operation, the valve receives a 24 V supply
briefly during installation. The power at the valve is reduced to a quarter after 120 ms.
