Fig. 7: Three-button PCB

The three-button PCB has two K-bus interfaces (1, CON400 & CON401), which are assigned ex factory.

The outer connection strips (2, CON600 & CON601) are used for power supply for the indicator lamps,

connection strip 4 is available for customer use. The bridges between the button PCBs are assigned ex

factory. The power supply has to be provided by the customer. One of the two N/O contacts of each

button is available for customer use via a connection strip (3, CON603). At a further connection strip (4,

CON602) three digital inputs are available for customer use, which are transferred via the K-bus. The 24

V supply has to be provided by the customer. The PCB also features a DIP switch (5, SW600), which is
