2.5 Functional Description
The P16800 is available in 1 and 2-channel versions and is used to detect speed sensor signals. The in-
put of the P16800 is designed in such a way that speed sensors with current or voltage output can be
connected. The outputs of the product can be configured as current or voltage outputs and behave
like a speed sensor for the controls. ➜Product Code, p. 7
P16810 1 input, 1 output
P16820 2 inputs, 2 outputs
P16840 2 inputs, 1 output, 1 DOT output
• The P16800 transmits galvanically isolated the pulse signal from speed sensors from the input to
the output. The product is used to double signals, i.e., to decouple them from existing measuring
circuits, or to protect controls from voltage loads on the speed sensor.
• P16840 only: The product can detect the direction of rotation of an axle or the direction of travel of
a vehicle.
• In the absence of input pulses, the product can detect the standstill of an axle or a vehicle.
• The reinforced insulation according to EN61140 ensures protective separation, and the protection
of persons from electric shock.
• The galvanic isolation protects the equipment and contributes to an unaltered transmission of the
measuring signals. This may improve the signal quality and decouple the controls.
EMC interference at the controls can thus be reduced.
• The P16800 can process signals from speed sensors and other pulse transmitters, e.g., flow sensors.
• The P16800 detects the pulse signals from speed sensor circuits without influencing them.
The absence of interaction can optionally be set for safety-related applications up to SIL4.
• The pulse transmission from the input to the output can optionally be set for safety-related
applications up to SIL2.
• Pulse transmission can be set as 1:1 or, with frequency division, as 2:1 (4:1 or 8:1 available ex
works). With enabled frequency division, the output signal has a pulse-pause ratio of 50%.
• The pulse signals can be inverted.
• The speed sensor’s voltage supply US at the input of the P16800 is required in order to set the
switching threshold during operation. US is not used to supply the P16800.
• The output is the binary image of the input signals (high/low level).
• The compact enclosure is suitable for mounting on 35-mm DIN rails and walls
(ZU1472 wall-mount adapter, optional ➜Accessories, p. 36).
• The following SIL products are suitable for safety-related applications:
◦SIL: P16811, P16812 in 1-channel version
◦SIL: P16821, P16822 in 2-channel version

Product Version with DOT Function
Device version P16840 generates a direction-of-travel (DOT) signal. The output of the first channel
(terminal 3.3) supplies the result of the input channel phase comparison as a DOT signal.
The output of the second channel reproduces the signal from the input of the second channel. With
the P16840, the outputs are galvanically interconnected. The inputs are galvanically isolated from
each other and from the outputs.

Channel 2‘

The phase shift of 2-channel speed sensors is approximately 90°.
With a rising signal edge at the input of channel 2, the output level of the DOT signal is set at the out-
put of the first channel.
The DOT signal is inverted when the polarity of a channel is changed (set DIP switch 1 at the output
➜DIP Switches, p. 29).

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 US and GND of the P16800. The threshold voltage for the level detection of the input is set via
input US. P16800 is supplied with energy via the VS 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.

6Equipotential bonding
With 2-channel speed sensors, US1 and US2 must each be connected. The voltage connected to US is
not used to supply the product’s inputs because the US input and the signal input are disconnected
from the input circuit of the P16800 with high resistance. In this case, the input remains unconnected.

2-channel speed sensor with current output
With speed sensors with current output, the signal currents are conducted via internal shunt resistors
of the P16800. The shunt resistors are protected against overload with diodes connected in parallel.
With the help of the external accessory diode jumper ZU1473, the current flow in the input circuit is
not interrupted when the plug is disconnected.

2Output driver for current and voltage
The P16800 is supplied via the VS terminal and GND (supply not shown in the diagram).
The output of the P16800 has two supply connections: VS and UB. If the UB terminal is used, then the
output driver is supplied by the voltage applied to UB via the diode network. If the UB terminal is open,
the output driver is supplied via VS and an internal voltage converter.
➜Voltage Output, p. 39 ➜Current Output, p. 39
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 UB 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.

ProLine P16800
17
2.7 Voltage Supply
P16800 is supplied via the output stages. The voltage supply is not galvanically isolated from the out-
put.
The typical voltage supply is nominally 12…24V (the permissible voltage range is 10…32VDC). The
voltage supply must be provided by a SELV, PELV power supply. The output stage and the associated
galvanically isolated input circuit are supplied via terminal VS or UB. The channel 1 and 2 supplies are
galvanically isolated.
The output of the P16800 can be supplied via a downstream controller or a power supply. The avail-
able currents (power output) are usually limited when power is supplied via a controller. If the current
is exceeded, an error message may be displayed in the controller. By selecting the terminal variant it is
possible to adjust the current through the downstream controller.
The following figures show the supply options for current and voltage outputs. The terminal options
shown differ in their use of terminal UB. If the UB terminal is not connected, the P16800 supplies the
output driver internally. This reduces the energy absorption and the temperature, so that the long-
term availability increases. If the downstream controller can evaluate reduced levels, the UB terminal
can remain open.
2.7.1 Supply of Active Current Output
Supply via the controller at terminal VS (active current output)
The current IS, which flows into terminal VS, is provided by the controller. The signal output voltage
UOut, or the load voltage of a channel is approx. 4V. The use of the standstill detection with an output
voltage of 7.2V is not possible in this terminal type.

ProLine P16800
18
2.7.2 Supply of Passive Current Output
Supply via the controller at terminal VS and UB (passive current output)
The current which flows from the controller and into the supply of the P16800, is shared as IS for
terminal VS and IB for terminal UB.
The current into terminal UB is equal to the current that flows out of terminal IOUT/UOUT.

If the load on the controller is to correspond to the load through a speed sensor, an additional power
supply may be used. Should the controller tolerate a higher load, the external supply source may be
omitted. In this case, change the configuration of the terminal to
