Model 504
Analog ramped PWM Valve Drive Board in a compact package (measures ~3.5" square); designed to drive most grounded coil and flow control valves.


  • 8 Independent adjustable parameters (via trimpots) allow fine-tuning of settings in-field
  • Can be driven with any source capable of 2.5V Neutral, 4V full-forward, and 1V full-reverse
  • PWM Outputs with thermal type current limit, high current SMARTFET capable of 2.5 amps
  • 3 Auxiliary outputs for out-of-neutral indication, directional valves, blocking valves, back-up alarms, brake-release, etc.
  • Current source output can drive dual and single coil grounded valves (flow control option available)
  • Regulated coil output current compensates for coil resistance changes due to temperature variations
  • Rugged potted assembly seals electronics from environment and prevents failures due to moisture ingression, shock, or mechanical damage
    •
  • Direct or remote mounting allows mounting directly to P-Q's Model 115 single axis joystick or externally
  • CE Compliance allows customers to sell into the European Community
