I/O module with CANbus interface, 
or with PWM output

  The intelligent CAN node with high protection class is
  particularly suitable for use in rough environments and in
  mobile applications. Due to its compact design and the
  universal mounting options, it can be positioned in the direct
  vicinity of sensors and actuators.

  With its compact and robust design, the intelligent and
  vehicle compatible CAN node allows the activation of
  proportional valves via PWM outputs. Mountable in the direct
  vicinity of sensors and actuators. Neither tough environmental
  conditions nor continuous mobile operation present any
  problems to this device.
