The digital display units in the HDA 5500 series are microprocessor-controlled display and monitoring units designed for control panel installation. Different versions are available with a maximum of three analogue inputs, an analogue output (adjustable 4 .. 20 mA or 0 .. 10 V) and up to four relay outputs.

The analogue input signals are displayed according to the settings selected by the user. Each of the relay output can be assigned to one of the inputs or to the difference between input 1 and 2. A Pt100 temperature probe can be connected directly. In addition, an optional frequency measurement is possible, e.g. by using the HDS 1000 (HYDAC rpm probe) for the measurement of the rpm speed of rotary components.
