The P304i pressure indicator and the P304c pressure controller are slide-in replacements for the now obsolete Dynisco indicator models UPR700 and UPR800 and controller models ATC770 and ATC880.  Simple retrofits require no rewiring and the operator and configuration parameters will be recognizable to those familiar with the Dynisco products.  The P304 series are purpose designed for plastic extrusion machinery, so they are simple to use and a great value.
