PYH SERIES
PERFECT FOR CONTROLLING RAPIDLY CHANGING PROCESSES LIKE PRESSURE AND FLOW
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 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.

• Free Software
The Fuji PYH is available with an RS-485 communications option. When you buy this option, you get FREE software that enables
you to run 31 controllers per port from your PC. This software has been designed with the novice user in mind. It’s easy to
operate and install using a simple diskette and a standard twisted shielded pair type wiring. The source code for this software is
also provided, which allows you to rewrite your system easily and inexpensively. If you’ve considered automating your plant,
but don’t want to spend a fortune on distribution control software, this is an ideal solution.
