Reed switch
The unit can be used with flowmeters which have a reed switch. To avoid pulse bounce from the
reed switch, it is advised to select REED LP – low-pass noise filter, which limits the maximum input
frequency (see
SETUP
4.1: FLOWMETER > SIGNAL[»29]). Make sure the contact resistance of the reed
switch is less than 1V@2uA=500 kOhm.

NAMUR signal
The unit is suitable for flowmeters with a NAMUR signal (units with PX cannot power the NAMUR
sensor). If required the NAMUR sensor can be supplied via the 8.2 V sensor supply (terminal P3),
only available with power supply type PD. See
SETUP
4: FLOWMETER[»29] for more information.
