Differential pressure controller 0-4000 Pa with Modbus RTU communication

Differential pressure controller 0-4000 Pa - 24 VAC or VDC supply

Product description

This is a differential pressure controller for fans. It controls differential pressure or air volume flow. Air velocity control is also possible in combination with a pitot tube connection set: PSET-PTS-200. The analogue output can control EC fans, frequency inverters or AC fan speed controllers. The output type is selectable: 0-10 VDC / 0-20 mA / 0-100% PWM. The four LED indicators provide a visual indication of the transmitter status and the controlled values. A typical application is to guarantee a constant volume flow of fresh air, regardless of the demand. The differential pressure setpoint and all other settings can be adjusted via Modbus RTU. The supply voltage is 24 VAC or 24 VDC. It can be used in the range of 0 to 4.000 Pa.
