User Selectable Input, 2A Output
The Dual Solenoid Multifunction Valve Driver provides accurate control of hydraulic proportional and directional valves used in mobile equipment and industrial processes. This multifunctional design will support inputs from a joystick potentiometer with or without centre tap, a standard potentiometer or commonly available control signals such as 0 to 5 Volts, 0 to +/-5 Volts, 0 to 10 Volts, 0 to +/-10 Volts, 0 to 20 mA, 0 to +/-20 mA or 1K potentiometer. The power supply connection is conditioned to withstand the harsh environment found in vehicular power systems. Maximum current output is 2 Amps, 1 Amp, 300 mA or 100 mA. A high-low range input provides reduced output for limited operation. The driver is potted and packaged in a metal base. It holds an IP65 rating. Flat tab style or screw terminal connections are provided.
Features:
- High-efficiency PWM with superimposed dither
- High-speed power up permits the entire electronics package to be powered from safety interlock trigger switches or joystick mounted micro switches when safety is of primary concern
- High low range input provides reduced output for limited operation (i.e. training or operation in tight spaces)
- Pump enable output active only when the joystick is active
- Suitable for harsh environments (IP65 protection rating)
- Electronic overload protection Static and surge protection built in
- EMI/RFI resistant
- Current sensing circuit maintains output current regardless of changes in input voltage and coil resistance
- Adjustable electronic joystick deadband jump
- Adjustable minimum current (0 to rated Amps) and maximum current (0 to rated Amps)
- Maximum current outputs include 2 A, 1 A, 300 mA, 100 mA or other values on request
- Adjustable asymmetrical ramps (0.01 to 5 Seconds) with symmetrical ramps user selectable
- Centre null to accommodate joystick or potentiometer centering errors
- Master/slave option permits only one axis to operate at a time
