5.3.3. Connecting a 0(4)-20mA transmitter in 3-wire-technology
with individual transmitter supply
without individual transmitter supply
5.3.4. Connecting a 0-1V, 0-2V or 0-10V transmitter in 3-wire-technology
with individual transmitter supply
without individual transmitter supply
5.3.5. Connecting a 0-1/2/10V or 0-50mV transmitter in 4-wire-technology
with individual transmitter supply
without individual transmitter supply
(Note: Sig- and
–Uv must be the same potential)
5.3.6. Connecting a frequency- or rotation-signal
M
easuring frequency or rotation three different input signals can be selected in the device’s config-
uration. There is the possibility of connecting an active signal (= TTL, ...), a passive sensor-signal
with NPN (= NPN-output, push-button, relay, ...) or PNP (= a PNP output switching to +Us, high-
side push-button, ...).
When configuring the device with a NPN switching output, a pull-up-resistor (~11k
Ω referring to
+3.3V) is connected internally. So when you use a device with NPN
output You don‘t need to con-
nect a resistor externally.
When configuring the device with a PNP switching output, a pull-down resistor (~11k
Ω referring to
GND) is connected internally. So when you
use a device with PNP output You don‘t need a resistor
externally.
It may be that your measuring-signal source needs the connection of an external resistor e.g. the
pull-up-voltage of 3.3V is not enough for the signal source, or you want to measure in the top level
