HYDAC pressure transmitter Digital Display Unit HDA 5500
Description:
The Digital Display Unit HDA 5500 is a microprocessor controlled display and monitoring unit designed for control panel mounting. Different versions are available with a maximum of 3 analogue inputs and 4 relay outputs. The analogue input signals are displayed according to the measuring scale selected by the user. Each of the 4 relay outputs can be allocated to each of the 1 to 3 sensor
inputs or to the differential between input 1 and 2. The PT100 temperature probe can be connected directly to the unit. There is
also an option for frequency measurement using the HDS 1000 (HYDAC rpm probe), for example, to measure the speed of rotating
components. The analogue output is standard and adjustable for 4 to 20 mA or 0 to 10 V.
