2.6 Input/Output
Speed sensors with voltage output and current output can be connected at the input of the P16800.
2-channel speed sensor with voltage output
With speed sensors with voltage output, the voltage supply of the speed sensor is connected to the
inputs U
S
and GND of the P16800. The threshold voltage for the level detection of the input is set via
input U
S
. P16800 is supplied with energy via the V
S
terminal and GND (not shown in the diagram).
The output signals of the speed sensor are connected at the U and GND voltage inputs of the P16800.

Equipotential bonding
With 2-channel speed sensors, U
S
1 and U
S
2 must each be connected. The voltage connected to U
S
is
not used to supply the product’s inputs because the U
S
input and the signal input are disconnected
from the input circuit of the P16800 with high resistance. In this case, the input remains unconnected.
