While most temperature control systems can be maintained sufficiently with the twice-per-second sampling rate found in other controllers, the PYH reads the process variable ten times per second and makes control decisions at the same rate. That's what makes this process controller well-suited to control pressure, flow rates, and temperature of low mass systems like a single metal filament.
With a fast sampling rate and full PID control, the PYH minimizes overshoot and oscillation around the setpoint which normally would occur before most controllers would detect them.
The PYH can also handle slower responding processes and offers autotuning capability to optimize control parameters. For remote operation and factory automation, up to 31 separate controllers can be monitored at the same time. Setpoint and other control values can easily be reset at your command with free custom software.
The PYH offers another unique feature called position feedback. This capability lets you know and control the exact position of a valve at any time. To initiate position feedback, the operator simply indicates two valve positions—fully open and fully closed. The controller does the rest, keeping track of the valve position at all times. Knowing the precise position of the valve is critical in boosting system performance and avoiding motor burnout where a controller without position feedback might try to open or close a valve that's already reached its limit.
