PR 2224 Valve Controller

• multifunction user interface consisting of three push buttons and a 3-digit LED display
• all parameters are protected against unauthorized changes with a password

Common Applications for a Valve Controller

• control and regulation of single- or double-coil hydraulic and pneumatic proportional valves
• for accurate oil flow regulation, linear soft acceleration and deceleration, modulated output signal, and programmable deadband
• highly suitable for joystick regulation of A/B movements
• where changes to A and B need direct selection 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 according to order schedule, joystick / potentiometer, or a special non-programmable input
• digital inputs for external control functions
• pulsating current output prevents the 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 adapt for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying
