DIFFERENTIAL PRESSURE TRANSMITTERS DPT-MOD Series Differential pressure transmitter with Modbus communication and Input terminal The DPT-MOD differential pressure transmitter for air conforms to Mod bus over serial line protocol, using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-MOD to connect directly to a field communications network. DPT-MOD requires less wiring than traditional 3-wire transmitters, since multiple devices can be connected on serial line. The DPT-MOD includes an Input terminal that enables reading of mul tiple 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-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-MOD does the work of three transmitters.
