The setpoint signal is supplied as a 0 to 5 Vdc or 4 to 20 mA analog signal.
All signals are supplied via the 15-pin D-Connector. There is also an
optional local operator interface (LOI). When the LOI is used the setpoint
signal is provided by the LOI.
The Brooks electrical interface is designed to facilitate low-loss, quiet
signal connections. Separate returns (commons) are supplied for the

are electrically connected together on the PC board.
