DPT-Ctrl-MOD Differential Pressure Controller
Produal DPT-Ctrl-MOD
Differential pressure controller with PID control loop and Modbus RTU communication. It incorporates a configurable 0-10 V input, NTC 10k, Pt1000, Ni1000/(-LG) and potential-free contact.
The DPT-Ctrl-MOD Modbus differential pressure or airflow controllers are designed for building automation systems. These controllers allow for the control of constant pressure or airflow from fans, VAV systems, or dampers. For airflow control, a fan manufacturer or a common measuring probe with a K-value can be selected. The DPT-Ctrl-MOD incorporates an input terminal that allows the reading of multiple signals, such as temperature or control relay signals, via Modbus. The input terminal has an input channel designed to accept 0-10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential-free contact) signals.
