HDA 5500 User Manual

10 Output response

The HDA 5500 has a through analogue output, the signal of which is proportional to an input
signal. In addition, depending on the model and type, the HDA 5500 is available either
without switching outputs, or with two or four switching outputs.

10.1 Analogue output

On the analogue output a 4..20 mA or 0..10 V signal is available. The signal is proportional to
the input signal of one of the sensors or of the differential value. Both the allocation of the
output signal to sensor or differential value and the type of signal can be adjusted during
normal operation.
For setting „diFF" (Analogue output allocated to differential value (sensor 1 – sensor 2))
reference for values of sensor 2 = values of sensor 1 is an analogue output signal of 12 mA
or accordingly 5 V. From there values of sensor 2 < values of sensor 1 are shown with
signals of 0 .. 12 mA or accordingly 0 .. 5 V and values of sensor 2 > values of sensor 1 are
shown with signals of 12 .. 20 mA or accordingly 5 .. 10 V.
