Weboutputs, proportional controllers are also available with proportional analog outputs, such as 4 to 20 mA or 0 to 5 Vdc. With these outputs, the actual output level is varied, rather than the on and off times, as with a relay output controller. One of the advantages of proportional control is simplicity of operation. It may require an operator Web13 de fev. de 2024 · The controller can be programmed to send an output signal proportional to the current distance from the goal point—a large output if far away, a small output as the goal gets closer. This is proportional gain. Figure 1. A red stoplight at an instersection is like a set point/goal position. Image used courtesy of Canva.
