PR electronics Valve Controller 2224

Advanced features Multifunction user interface consisting of three pushbuttons and a 3-digit LED display. All parameters are protected against unauthorized changes with a password. Application Control and regulation of single- or double-coil hydraulic and pneumatic proportional valves used for accurate oil flow regulation, linear soft acceleration and deceleration, modulated output signal, and programmable deadband. Is highly suitable for joystick regulation of A/B movements. Where changes to A and B need to be selected directly or according to the value of an input signal. Technical characteristics During operation the display shows the present output signal as a % of the I valve. Programmable current or voltage input for standard signals acc. to order schedule, joystick / potentiometer or a special non-programmable input. Digital inputs for external control functions. A pulsating current output prevents the connected valve from sticking. Optional programming of the modulation frequency (PWM) between 8 and 400 Hz. Multiple adjustable parameters such as output currents, ramp times, jump values, chopper frequency, reversal, deadband, and ON/OFF functions. Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR's 7023 adaptor and 7024 mounting keying.
