Series DPT-MOD Differential Pressure Transmitter Monitors DP and gives Modbus output

The Series DPT-MOD Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure. The 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-MOD to connect directly to field communication network. the benefit of DPT-MOD is that it 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 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.
