Pressure (P) input from the MV sensor, differential pressure (DP) input from the MV sensor,
connections for temperature (T) input from a customer-supplied RTD/PRT -or – a single
Static Pressure Sensor with RTD/PRT connections. Alternatively, you can purchase the flow
computer without an integral sensor.
Either single digital output (DO) or four on-board I/O channels [two on-board I/O channels
you can individually configure as either digital input (DI), digital output (DO), or pulse input
(PI) and two on-board I/O channels you can individually configure as either analog input (AI)
or analog output (AO)].
