Table 3-4 Connector -X32
Pin Signal type Signal designation
1 DO_0* Binary signal 0
2 1M24
3 DO_1* Binary signal 1
4 1M24
5 DO_2* Binary signal 2
6 1M24
7 DO_3* Binary signal 3
8 1M24
Signals DO_0 to DO_3 of connector -X32 are identical to signals DI_0 to DI_3 of connector -X231, which are supplied from
the PSA. An LED signals the logic state of the respective signals. These signals are not wired to the PADU8 interface.
Table 3-5 Connector -X33
Pin Signal type Signal designation Signal direction PADU8 (option G66)
1 DO_EO External binary signal 0 → -X5:1
2 1M24 -X5:2
3 DO_E1 External binary signal 1 → -X5:3
4 1M24 -X5:4
5 DO_E2 External binary signal 2 → -X5:5
6 1M24 -X5:6
7 DO_E3 External binary signal 3 → -X5:7
8 1M24 -X5:8
Four binary plant signals can be wired via connector -X33 for diagnosis with the PADU8.

3 1M24 Ground
4 1N24 -24 V
The internal supply voltlage is connected at connector -X34, from which the 1P15 and 1N15 supply voltages are generated
for the analog amplifiers. At the same time, comparators monitor these two voltages for undervoltage.
