Differential Pressure Controller DPC200 Diagraphm element with differential transformer Measuring ranges: 0...50, 0...500, 0...1000, 0...2000, 0...4000 [Pa] LCD-Display Analog output 0...10 V Controlling mode or measuring mode selectable Controlling mode with PI algorithm 2 setpoints adjustable Selectable measurements (differential pressure or volume flow) Selectable units (metric or imperial) Maximum output voltage adjustable Open Collector Alarm output (measuring and control mode) Compact plastic housing IP 54; UL 94 HB Supply voltage 10...30 Vdc or 24 Vac (+/-15%) Application The differential pressure controller DPC200 measures low pressure of non-aggressive gases, particulary of air. The customer can use an analog signal (0...10V). The device offers two different settings. On the one hand the output signal stands for a pressure proportional signal during measuring mode or volume flow square root signal. And on the other hand the output signal stands for a PI closed-loop control signal for differential pressure during control mode or volume flow during control mode. This static pressure transducer with controller is primarily intended for air conditioning systems, room pressure control and filter control with continuously varible speed fans. The DPC has an additional alarm output (open collector) for limit value monitoring or for filter monitoring next to the analog output.
