DPT-IO-MOD

Differential pressure transmitter with Modbus communication and Input terminal

The DPT-IO-MOD differential pressure transmitter for air conforms to Modbus over serial line protocol using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-IO-MOD to connect directly to a field communications network.

DPT-IO-MOD requires less wiring than the traditional 3-wire transmitters since multiple devices can be connected on serial line.

The DPT-IO-MOD includes an Input terminal that enables reading of multiple other signals such as temperature or control relays over Modbus. The Input terminal has two input channels designed to accept 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals. For example, DPT-IO-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-IO-MOD does the work of three transmitters.

DPT-MOD

Multifunctional differential pressure transmitters with air flow measurement and Modbus communication

DPT-MOD is a multifunctional transmitter for measuring volume flow, velocity, and static and differential pressure. The measurements can be read and the configuration done via Modbus communication. DPT-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on serial line. DPT-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.

DPT-MOD series devices include: • Two selectable functions: o Measure and monitor in-duct volume flow, velocity or differential pressure o Measure and monitor air flow across centrifugal fans • Multiple 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 • Modbus communication protocol

DPT-MOD series device options offer: • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
