The SDU module supports encoder voltages of 5 V, 8 V, 10 V, 12 V, 20 V and 24 V, that
are monitored internally according to the selected configuration in SafePLC2.
If an encoder system is not supplied via the SDU module, it must be ensured that the
GND of the encoder is connected to the GND of the SDU module. If the GND of the
encoder is only at pin 2 of the D-sub connector, the terminal UE- (terminal X13) must
also be connected to GND (see also chapter 7.5). Above that the supply voltage of the
encoder must be connected to pin VCC+ (pin 9 of the D-sub connector). The terminal
UE+ then remains unconnected.
The encoder supply must be protected with a fuse of max. 2A.
SAFETY NOTE • The GND connection of the encoder must be connected to the GND of
the SDU.
