Systemair Pressure controller PCA 1000D2 - pressure or airflow, 0-1000Pa, 24VDC

Demand controller for pressure and constant flow ventilation • Demand controller for EC-fans or e.g., a frequency inverter. • Possible control modes -Variable air volume (VAV) -Constant air volume (CAV) • User friendly menu, easy setup • Supply voltage directly from the fan. No additional supply voltage is necessary. Technical specification • Controlled output signal: 0-10 V (Imax = 0.3mA) • Voltage supply with polarity reversal protection: 10-24 V DC(Imax = 6 mA) • Adjustable measuring range 0-1000Pa • Pressure ports + / -: for ∅ 5mm hose adapters ∅ 6 mm • Enclosure class IP54 The sensor control module for differential pressure and volume flow measures and indicates the pressure or, optionally, the volume flow in a ventilation system. The calculation of the volume flow is performed by entering the K-factor of the application. Depending on the desired setpoint value and control range, the sensor control module generates 0-10 V to control the EC fan or e.g., a frequency inverter. The sensor control module i...
