DPT-Ctrl-MOD Air handling controller with Modbus - 1

USER-FRIENDLY MEASURING DEVICES air handling controller dpt-ctrl-mod Multifunctional PID controller with differential pressure or air flow transmitter and Modbus communication The DPT-Ctrl-MOD series PID controllers are engineered for building automation in the HVAC/R industry. With the built-in controller of the DPT-Ctrl-MOD it is possible to control the constant pressure or flow of fans, VAV systems or dampers. When controlling air flow, it is possible to select a fan manufacturer or a common measuring probe that has a K-value. DPT-Ctrl-MOD series devices include: • PID-controller o Control differential pressure or air flow in duct or across centrifugal fans o All parameters (PID) are adjustable via menu and Modbus • Multiple field selectable measurement units: o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min o Pressure: Pa, inWC, mmWC, kPa, mbar • Control output: Voltage (0-10 V) • One external input: voltage, thermistor or binary input • AVT series air velocity transmitters • DPT-Flow series air flow transmitters • DPT-R8 series 8-range differential pressure transmitters • DPT-MOD series differential pressure transmitters with Modbus configuration • DPT-Ctrl series air handling controller DPT-Ctrl-MOD series devices are commonly used in HVAC/R systems for: • Controlling differential pressure or air flow in air handling systems • VAV applications • Controlling parking garage exhaust fans model summary Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 4.0 2017
