HDA 5500

Available versions:
Standard; with sequential analogue input for SMART sensors

The digital display units of the HDA 5500 series are microprocessor-controller display and monitoring units, conceived for switch panel installation.   Up to three analogue inputs plus one analogue output (4 to 20 mA or 0 .. 10V) and up to four relay switching outputs are available. The analogue input signals are displayed according to the settings selected by the user. Each switching output can be assigned to one of the outputs or to the difference between input 1 and 2. One PT100 temperature probe can be connected directly. In addition, an optional frequency measurement is possible, e.g. by means of the utilisation of the HDS 1000 (HYDAC rpm probe) for the measurement of the rpm speed of rotary components.   Depending on the version, the option also exists of attaching SMART sensors (so-called condition monitoring sensors). SMART sensors are a sensor generation from HYDAC which can output several different measured variables.
