Basic electronic module ME03 / 2-fold monostable
Construction
A basic electronic module consists of a distributor module (back-wall bus) and a function module. Both
modules are contacted via a 14-pole board-to-board connector.

The functional module, like the electronics modules of the Point I/O system, may be pulled off and
plugged on during operation. To ensure the switching operation, 24 V is applied briefly to the valve on
plugging on. The power consumed by the valve is reduced to one quarter after 400 ms.
