P4CG2001C001 Parker Hannifin Industrial Automation Components

The Parker EPP4 programmable electronic proportional regulators allow for regulation of outlet pressure proportionally to an electrical control signal. This unit utilizes Calys software to configure all parameters. The communications cable 496449 is required and permits the communication between the unit and a PC. This free, user friendly software enables live monitoring, recording and upload of the parameters in an Excel file, set pressure scale (PSIG, bar, Mpa), adjustment of minimum and/or maximum pressure limits, adjustment of control signal (0-10V or 4-20mA), adjustable positive or negative alarms (including delays and timing), complete and interactive help files, etc. The EPP4 units come standard with an "auto-safe" feature which a special electronic arrangement that limits the overheating of the filling coil and consequently prevent any damage to it caused by an excess of temperature. The auto-safe function automatically operates after a few seconds when the control signal remains applied without input pressure.       The auto-safe system is disabled as soon as the control signal or input pressure is correct    The auto-safe system is working alone and is not dependent of alarm signal Internal pulse width modulated valves control the output pressure proportionally to a field convertible analog input control signal of 0-10V or 4-20mA. The EPP4 unit is comprised of a traditional servo-operated pneumatic pressure regulator, where the pilot chamber is fed by one or the other of two pulse width modulated 2-way solenoid valves. An internal pressure sensor measures the output pressure of the regulator and provides a feedback signal to the controller. Any differences between the control signal and the feedback signal is converted to a digital signal to energize one or the other 2-way valves to correct the position of the regulator.
