Display Monitoring Units – HDA 5500

Furthermore, different versions are available with a maximum of 3 analogue inputs, an analogue output (4 .. 20 mA or 0 .. 10V) and up to 4 relay outputs. The analogue input signals are displayed according to the settings selected by the user.

Therefore, each of the relay outputs can be allocated to each of the sensor inputs or to the differential between input 1 and 2. A PT 100 temperature probe can be connected directly to the instrument. What’s more, there is an option for frequency measurement using the HDS 1000 (HYDAC rpm probe), for example, to measure the speed of rotating components.

HYDAC SMART sensors, for the transmission of several values

Furthermore, depending on the model, it is also possible to connect SMART sensors (condition monitoring sensors). SMART sensors are a generation of sensors from HYDAC which can transmit several different measured values.

Features:
