An industrial control system is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted cont
Panel mounted controllers with integral displays. The process value (PV), and setvalue (SV) or setpoint are on the same scale for easy comparison. The controller output is shown as MV (manipulated variable) with range 0-100%.
