Control System is self-contained and has all of the features of the individual Level/Flow and Temperature systems plus Remote Set Point Control.

Remote Set-Point Control can be affected with the PROCON Level/Flow and Temperature Process Control System by using two Process Controllers.

The 4-20mA Analogue Remote Set-Point input allows various forms of cascade control to be implemented between linked or interactive control loops.

The process set-point can be Local and Remote or Dual, selected from the front panel, or in response to a logic input.

When Dual Set-Point is selected the function can be ratio or bias action.

A Programmable Logic Controller (PLC) 38-350 is also available. It can be used with the Process Interface 38-200 to

provide an alternative control method with on/off elements to the standard Process Controller 38-300.
