10 Output response
The HDA 5500 has an analogue output which is proportional to an input signal. The
analogue output can be allocated to each of the signals (rel. change in viscosity, rel. change
in dielectric constant, rel. humidity, temperature when device HLB 1000 is selected, or CH1,
CH2, CH3 or CH4 when device CS 1000 is selected).
10.1 Analogue output
On the analogue output a 4..20 mA or 0..10 V signal is available. This signal is proportional
to the input signal of the relevant measured variable (see Point 7.2). The signal can be
adjusted as required.
10.1.1 Analogue output set to 4..20 mA
Connection example for analogue output set to 4..20 mA.
If the input signal is less than 3.7 mA, a cable break is detected. The initial value of the
measuring range will then flash constantly and the analogue output (only in 4 ..20 mA mode)
continually supplies a current of 3.5 mA.
10.1.2 Analogue output set to 0..10 V
Connection example for analogue output set to 0..10 V.
