This control type is usually a variation of VDC. Common values are: 0-10 VDC 2-10 VDC It is common to also have a 0-20/4-20 mA output from a controller. immtrac healthcare providers

"Webvariable is often called the set point. The control signal is thus a sum of three terms: the P-term Dwhich is proportional to the errorE, the I-term Dwhich is proportional to the integral of the errorE, and the D-term Dwhich is proportional to the derivative of the errorE. The controller parameters are proportional gain. K, integral time. T. i " - On off vs proportional control
