4.3.2 Internal Analog Output
Board
For those needing more than one analog output, Isco offers the
Multiple Analog Output Board, which is installed inside the
flow meter. This board provides from one to three isolated analog
outputs. You can order the board with three, two, or one circuit
installed. You must specify this when the flow meter is ordered.
The board is compatible with the existing external 4-20 mA
output box (60-1784-039). A flow meter can use either the
internal board, the external box, or both, for a maximum number
of four analog outputs.
Input Connector 6-pin male M/S
