Interface module
7.3 Interface module SB61
All outputs have a common reference potential in delivery state, i. e. each terminal pair X11
to X18 is equipped with two short-circuit plugs.
Position of the jumpers
The jumpers (short-circuit plugs) are located in enclosure behind the lid section facing away
from the LEDs. These are only accessible after the interface module has been removed.
The potential assignment between the plant and system side is defined as follows:
Table 7- 3
The input circuits are additionally electrically
isolated
Inputs with common reference potential
n = number of input 1 to 8
1)
Note
The potential reference can be set separately for each input.
The interface module is designed only for vertical mounting positions due to thermal losses
to be dissipated.
