Potential Applications:

Boom Functions of Cranes & Wreckers

  • Controlling boom functions with a closed-loop PWM signal for excellent proportionality and fine metering
  • Input modules to convert discrete and proportional analog sensor into CAN


Wire Remote Controls

  • Allows remote control of boom functions for optimum user operating safety and visibility.

Cab Function

  • Broad line up of displays to integrate engine and vehicle controls and diagnostic information
  • Keypad for the cab to control lighting
  • Engine and Transmission Control
  • Ability to monitor the engine and transmission

Chassis Functions

  • Head lights, brake lights, park lights, turn lights and console lights
  • Work lights (capable of driving HID lights)
  • Fans and blowers
  • Pumps
  • Wipers
  • PTO (Power Take-Off)
  • High current multiplexed relay modules to drive up to 40 amps per output

Misc Functions

  • Smart Datalogger up to 4GB with optional Wi-Fi communication to log critical events
  • Fleet management via a fully functional Telematics system including the ability to download in application code remotely to the vehicle
  • CAN Bridge modules to allow different CAN networks to safely transfer required information between networks

Future Flexiblity

  • User friendly software tools to allow you to modify and update your control system as required


Cost Effective

  • Distributing the vehicle controls will significantly reduce wiring harness and slip-ring costs
  • Reduced Installation Cost
  • Lower Cost of Ownership
  • Reduced Warranty Cost
    • Reduced wiring
    • Robust products

Increased Performance

  • Smart load shedding allows prioritization of critical functions when multiple power requests are made by operator
  • Closed-loop current control (up to 5mA accuracy) for fine metering and a smooth swing / slew

Improved Efficiency

  • Ability to coordinate functions (lift, extend, etc.)
  • Ability to coordinate subsystem (hydraulic, lighting and powertrain) to maximize fuel efficiency

Enhanced Flexibility

  • User-friendly software tools allows you to modify functionality in the field
  • Telematics allow you to download new functionality remotely from the web
  • CAN based, distributed system allows module to be added quickly to the system
