In the digital input configuration, the "Contact" option must be set to
"Ext. voltage supply".

For the voltage supply to sensors with DC 24 V, the optional board for voltage supply (part no. 00592963)
must be integrated into the device.
b
The connection variants for transistor switching outputs (NPN / PNP) are especially important for the flow
measurement via impeller sensor (type 406020, part no. 00525530, 00525531) at inputs IN 2 and IN 3
(pulse frequency inputs). However, other sensors with transistor switching output can also be connected.
