Output driver for current and voltage
The P16800 is supplied via the V
S
terminal and GND (supply not shown in the diagram).
The output of the P16800 has two supply connections: V
S
and U
B
. If the U
B
terminal is used, then the
output driver is supplied by the voltage applied to U
B
via the diode network. If the U
B
terminal is open,
the output driver is supplied via V
S
and an internal voltage converter.

The signal output OUT can be parameterized as current or voltage output via DIP switches. With an
active standstill detection and detected standstill (frequency < 1 Hz), a constant voltage of 7,2 V is
measured at the output. The U
B
terminal must be connected in this mode. To activate the standstill
detection, the voltage output must be selected via the DIP switches. The switching output SW is a
diagnostic switch (switch) and, when it is open, signals a detected error. All output connections are
protected with bipolar suppressor diodes.
