Electronic control units

The birth and the successive development of Elen start with the conception and the realization of the ECUs for agricultural vehicles. Te ECUs are committed to the management and control of special on-board operations, and implement diagnostic and safety functions in order to safeguard of the devices connected in the system. The correct operation and the parameters setup can be managed by mean of the dedicated external diagnostic tester. They are suitable for the external or cabin installation. The internal resination process (on request) guarantees the IP67 grade of protection. Similarly to the on-board computers, they use microprocessors and configurable softwares designed in way to meet the requirements of our customers and comply to the CE statements for the automotive field.

CPA ECU – rear lifter

Item code AA000060

Ideal for tractors of middle-low power. It controls in active mode the strain and the position of the tool by mean of 2 potentiometers mounted on the dashboard. The strain and position detection is performed using two Hall effect sensors Type AA.02.0001. Possible cables kit supply.

CFE ECU – electromagnetic clutch

Item code AA000067

It activates an electromagnetic clutch in a gradual way over a predtermined rpms threshold. It disconnects the clutch when an high torque is detected. Applicable on Baruffaldi’s electromagnetic clutches.

Suspensions ECU

Item code AA000098

Suspended Axle controller for agricultural tractors. Suspension regulation within a specified oscillation range managed by mean of hydraulic circuit driving and oscillations control performed by AA.01.0017 type sensor. Operating modes: automatic or manual for service purposes.


Item code AA000110

The ECU drives, by mean of a push-button and a two-ways switch, two linear electromechanical actuators controlling their current consumption.An actuator manages the basket capsizing for the unloading of the collected grass. The other actuator manages the up-down movement of the plate carrying the mower’s blades.

Brake control ECU

Item code AA000065

It is used in agricultural tractors of middle-low power for the management of the articulated braking.
