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.
• • Front-programmable
  • mA, V, and Ω programmable input
  • Ramp times, jump values, reversal, chopper frequency, and deadband
  • 3-digit LED display shows I-valve % value
  • 1 or 2 channels
