Description –

The Position Controller accepts a 4/20 mADC Set Point Signal and a 3-Wire Potentiometer that is connected to the Valve which provides the Valve’s Position. The Position Controller compares the Valve Position Feedback signal to the Set Point and when the Valve Position doesn’t agree with the Valve Set Point by an adjustable amount, an Open or Close Contact closes to move the Valve to the Position of the Set Point. When the Valve Position matches the Set Point, both relay contacts open.
