DP & Air Flow Controller With Modbus - DPT-CTRL-MOD

      Categories Pressure, Differential Pressure & Flow Controller

      DPT-Ctrl-MOD enables to control constant pressure or flow of fans, VAV systems or dampers. In addition, the controller is fully programmable via Modbus.

      The DPT-Ctrl-MOD includes an Input terminal that enables the reading of multiple signals such as temperature or control relays over Modbus. The Input terminal has one input channel designed to accept 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals.
