This one controller now offers the bus and public transportation sector a very cost effective solution for all of the features and benefits associated with hydraulic fan cooling, while offering all the advanced safety features normally required in this market.

All inputs and outputs are fully protected against opens and short circuits with the valve PWM signal being modulated using SAE J1939 data signals and/or a discrete temperature sensor with user selectable settings for fan reverse and an alarm system interface.

The controller comes with a momentary 'Heat-Event' trigger input that interfaces with the engine bay installed heat detection circuit and directly forces the output to immediately drive to minimum fan speed for safety.

HFS-J-BUS PRODUCT FEATURES:

  • Pre-written Graphical User Interfaces for all modules
  • Operates with all OEM electro-hydraulic equipment
  • Sealed and protected to >IP67 ( NEMA 6P )
  • Unique 'Solid' potting with flame retardant materials
  • SAE J1939 & 1 x external discrete thermistor/switch contact
  • Heat event trigger switch input (drives to min fan speed)
  • Uni-direction fan control
  • Suitable for new OEM build or Repower / Retrofit / Upgrade applications
