4.3.6 Connecting a frequency- or rotation-signal
When measuring frequency or rotation three different input signals can be selected in the device’s configuration.
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 kΩ referring to +3.3V) is con-
nected 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 kΩ 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 frequency range. In this case
the input signal has to be treated like an active signal and you have to configure the device as „TTL“.
Hint: when connecting the device You have to take care not to exceed the limits of the input volt-
age respective the input current of the frequency-input.
