Hda 5500 With Frequency / Counter Function; Digital Display; Standard Display - Hydac HDA 5500-2-1-AC-000 Notice D'utilisation

HDA 5500
Connection example for transmitter with a 0..10 V as input signal,
e. g. HDA 5500-0-2-DC-000 with HDA 4746-B-100-000
(refer to chapter 16 Pin configurations):
HDA 4746-B-...

8.2 HDA 5500 with frequency / counter function

With Frequency, Start, Stop and Clear there are 4 inputs for square-wave signals. All inputs
are logically positive, i. e. they are set with a rising edge. The maximum amplitude of the
voltage is 24 VDC. The frequency range is from 15 Hz to 4 kHz.
Connection example for flow meter, e. g. HDA 5500-2-2-DC-000
(see also Section 16 Electrical connection diagrams):

9 Digital display

9.1 Standard display

According to the particular type, the following values can be set as the primary display. The
pre-set value concerned will be continuously displayed.
•
SEn.1 (measured value of sensor 1) or SEn.2 (measured value of frequency input)
The displayed value corresponds to the measured value and is proportional to the input
signal of the corresponding sensor. The values are linear between the lower limit and the
upper limit.
•
Min.1 (lowest value of sensor 1) or Min.2 (lowest value of frequency input)
The displayed value corresponds to the lowest value which has been measured since the
supply voltage was switched on or since the last reset.
