AP4570 Track-Hold & Peak-Hold Process Function
Brand: EurothermThe AP4570 offers two modes of operation - Track and Hold and Track and Peak-Hold. In "Track and Hold" operation the output tracks the input signal. When an external contact is closed, the input level is "saved" and its corresponding output signal is held indefinitely until the contact is opened. Releasing the hold switch (pins 8 and 11) allows the output to again follow the input.
The "Track and PeakHold" mode is similar to "Track and Hold" operation except upon contact closure (pins 8 and 11) the highest input is "saved" and the corresponding output is held until a higher signal level occurs.
