March 2019
6 Introduction
1.5 Inputs & Outputs (I/O)
The flow computer comes with base I/O from both the CPU and the built-in multi-variable (MV)
sensor.
Base I/O consists of:
▪
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)].

1.6 Power Options
You can power the flow computer using an external DC input, or an internal rechargeable battery
connected to a solar panel.
Important
Use only batteries supplied with the flow computer or sold by Emerson Remote Automation
Solutions as spare parts for this flow computer. If you substitute a battery you obtain elsewhere you
will void your certification unless it is the identical part from the same manufacturer as that
supplied with the flow computer from Emerson.
