5.3.6 Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s con-
figuration. 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 (~7 k
Ω referring to +3.3V)
is connected internally. So when you use a device with NPN output you don‘t need to connect a resistor
externally.
When configuring the device with a PNP switching output, a pull-down resistor (~7 k
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 fre-
quency range. In this case the input signal has to be treated like an active signal and you have to con-
figure the device as „TTL“.
When connecting the device You have to take care not to exceed the limits of the input
voltage respective the input current of the frequency-input.
