PT1 element

The PT1 element is a first-order proportional delay element used in closed-loop control technology. The input signal/potential at input 1 is amplified or attenuated by proportional-action coefficient Kp and delayed by delay time T, and is read out as the output signal/potential at output 2. In order to keep circuit wiring as straightforward as possible, required earthing (0 V) and supply voltage are not led out as terminals, but rather wired internally.
