AX022002 CAN-Dual Valve Controller

Dual Valve Controller, SAE J1939 

The CAN-2 Valve Controller (CAN-2O) is a highly programmable controller, allowing the user to configure it for their application. It must be integrated into a CAN J1939 network of controllers. Its sophisticated control algorithms allow for open or closed loop drive of the proportional outputs. All logical function blocks on the unit are inherently independent from one another, but can be programmed to interact in a large number of ways. While Figure 1A shows the hardware features, Figure 1B shows the logical function blocks (software) available on the CAN2O. All setpoints are user configurable using the Electronic Assistant®.

The CAN-2O has a number of built-in protection features that can shut off the outputs in adverse conditions. These features include hardware shutoffs to protect the circuits from being damaged as well as software shutdown features that can be enabled in safety critical systems.


The controller is designed to meet the rugged demands of mobile equipment and heavy duty industrial machine control applications. These applications include, but are not limited to the following:

  • PID Closed Loop Valve Control
  • Hydraulic Valve Control


  • Two independent software controlled outputs selectable as: Proportional Current (up to 3A); Hotshot Digital; PWM Duty Cycle; Proportional Voltage; or On/Off Digital types (4A)
  • 9…60VDC (12VDC or 24VDC nominal)
  • 1 CAN (SAE J1939) port
  • Aluminium enclosure with integral 12-pin connector
  • IP67
  • Electronic Assistant® for user programmability
