DPT-IO-MOD Differential pressure transmitter
he 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.
