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.
