DIFFERENTIAL PRESSURE & VOLUME FLOW CONTROLLER - DPC200-MOD Electromechanical diaphragm measuring system Configuration via Modbus communication Selectable measurements (differential pressure or volume flow) Selectable units (Pa / InH20 or m3/h or cfm) Selectable control mode or measuring mode Control mode with adjustable: setpoint, maximum output voltage, P and I parameterd for PI-algorithm, direct or inverse sense Adjustable k-factor for volume flow calculation Analog output 0...10 V Alphanumeric LCD-display Supply voltage 22...26 Vdc; 24 Vac (+/-10%) Compact plastic housing IP 54 Elektrischer Anschluss The DPC200-MOD has been developed to bundle functions needed in the HVAC industry into one device. As a precise differential pressure sensor it can transmit measurements for both pressure and air flow. The integrated 1 DPC200-MOD + 15...30 Vdc oder 24 systems, where PI control logic is an important component in decentralized closed loop controlVac (±15%) Versorgungpressure and air flow 2 have to be constantly controlled. - GND 3 The additional Modbus RTU interface is intended for the digitalisation of industrial processes. All device parameters + 0...10 Vdc Ausgang ΔP can be read and written with the Modbus RTU interface. 4 - GND For direct analog processing, a 0 ... 10 V signal output is available. This signal can be configured as a linear / square 5 B root measuring signal, or as a manipulated variable of the closed loop controller. MODBUS 6 It can be used, for example, in air-conditioning technology for controlling fans, monitoring room pressure or controlling filters. Connection diagram 1
