Thông số kỹ thuật:

The PA-22 PS is a compact programmable pressure switch and pressure transmitter. It offers continuous analog 0,5…4,5 V signal for process monitoring and switch functions to activate alarms or control relays at predetermined pressure levels.
The PA-22PS provides two independent switches for hi/lo control functions. These solid state
switches are not subject to wear and can be factory programmed in either PNP or NPN outputs. The optional DV-22 PP programmer (external supply) allows the user to easily change settings. This programmer can also be linked to a laptop/PC for use with Keller's "Pressure Switch Console" software.

The following characteristics can be programmed either at the factory, or by the User via the DV-22 PP:
