DPT-Ctrl-MOD Multifunctional PID controller with differential pressure or air flow transmitter With Modbus communication

DPT-Ctrl-MOD Multifunctional PID controller with differential pressure or air flow transmitter With Modbus communication

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.

Starting from November 2020, the device has a binary input to select between two user-adjustable setpoints. The desired setpoint can be selected, for example, with weekly clock, turn switch or key card switch.
