Potential Applications:

Pump Panel

  • Direct control of foam and CAFS (Compressed Air Foam System) systems
  • Video input from up to 4 cameras can be integrated with other machine control functions
  • Sealed CAN keypads for control of lights, pumps, and discharges
  • Pressure governor control
  • Sunlight readable displays can be used to integrate and control multiple panel mounted subsystems

Cab Functions

  • Broad line up of displays to integrate engine, vehicle, and implement controls with integrated diagnostic information and video
  • Cab mounted keypads to control lighting, sirens, wipers, HVAC and transmission
  • Externally mounted keypads for remote entry and cab lift
  • Direct engine, PTO and transmission interface
  • Electrical power distribution and control (up to 40 amps per output)
  • High current power modules with integrated current sensing to drive lights, wipers, and HVAC controls

Body Control

  • Distributed lighting control dramatically reduces wire harness size and complexity
  • Compartment lighting and door monitoring can be integrated       
  • Sealed keypads for outrigger controls

Aerial Control

  • Precision control of aerial hydraulic functions
  • Eliminate slip rings with CAN based multiplexing
  • Multiple control stations
  • Compact and rugged modules can be mounted directly to aerial booms or baskets
  • Modules can be configured as stand alone controllers for implements and other subsystems
  • Customized hardware and software for direct control of popular hydraulic valves
  • Sunlight visible, rugged, and sealed displays for use on aerial baskets

Advanced Applications

  • Smart Dataloggers with up to 4GB and optional Wi-Fi communication to log critical events
  • Real time remote vehicle diagnostics and software update via a fully functional Telematics system
  • Aerial envelope control algorithms using a 32 bit processor

  • Easily interface with 3rd party devices for overall system integration and control


Cost Effective

  • Distributing the vehicle controls will significantly reduce wiring harness cost size and complexity
  • Integrated cab controls reduces complexity and frees up valuable dashboard space
  • Integrated pump controls free up valuable pump panel space
  • Up to 4 video channels per display eliminates the need for back up camera monitors
  • Reduced Installation Cost
  • Lower Cost of Ownership
  • Reduced Warranty Cost
    • Reduced wiring
    • Robust products

Increased Performance

  • Closed-loop current control (up to 5mA accuracy) for fine metering and control of aerial devices
  • Flexible integrated video allows automated selection of video and/ graphics

Enhanced Flexibility

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