Description

Outstanding quality, suitable for high-power devices as well. The 50+ A relay disconnects the device, so it can never drain the battery.

Key features and benefits

  • Maximum current transfer: the 50 A rating and generously sized, pure copper conductors ensure minimal voltage drop and cool operation, even under continuous load.
  • Active battery protection: the 50+ A relay fully disconnects high-power consumers after the ignition is switched off (or when the control signal stops). No more starting problems because a device was left on.
  • In-cab power supply: the system includes a separate 15 A supply for the cab, ideal for displays, terminals and other smaller peripherals.
  • Built-in protection: the relay control circuit is protected by a separate 1 A fuse, so the control electronics and the vehicle’s own electrical system are kept safe.
  • Standard connection: the in-cab cable comes with a standard 9-pin connector, compatible with most market standards, which makes installation and replacement easy.

Adapters for different tractors

Measuring the steering shaft diameter with a caliper to choose the right adapter size

To ensure you select the correct adapter, the most reliable method is to remove the steering wheel and measure the diameter of the splined shaft, as shown in the image.

In most cases, the spline count is 36; therefore, the diameter is the determining factor. Based on our experience, dimensions are consistent across certain brands.

Models for which the data in the table below are highly reliable:

  • John Deere and newer machines from the CNH Group: A+

  • Claas and Massey Ferguson: N

When do I need a 4G router?

Add an external 4G router to your kit if: 

  • Tablet has no LTE modem: Your tablet lacks a built-in SIM slot, and you don’t want to rely on your phone’s mobile hotspot.
  • Weak signal coverage: The external antennas provide a stable internet connection in remote fields where standard mobile phones often lose reception.
  • Section controller setup: You are using an extra control board for automatic section control or sprayer management. This setup utilizes the router’s Ethernet hub function, where a third Ethernet cable is connected directly to the SC to ensure seamless communication between the devices.
