Interface module
7.3 Interface module SB61
SIMATIC TDC hardware
192 System Manual, 08/2017, A5E01114865-AL
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.
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 Position of the short-circuit plug (jumper)
Reference potential of inputs
Position of the short-circuit plug (jumper)
The input circuits are additionally electrically isolat-
Connector X1n

:2:3 inserted
Inputs with common reference potential
Connector X1n :1:2 and X1n :3:4 inserted
1)
n = number of input 1 to 8
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.
