MEB Options
2-DI/DO MEB
Power for each discrete output is customer supplied and is independent of
the flow computer's input power, unless it is connected to an internal
board. Each signal provided by the board is an open drain FET output
contact closure detected as a level signal. Some optional boards may require
the internal use of one or more of the discrete outputs, making them
unavailable. The discrete outputs are identified in the table below.
