CJVD-10 CANopen AMP Junior Power Timer (JPT) valve driver

A new approach to integrate existing hydraulic valves with CANopen®-network.

This unit gives a very cost efficient CANopen® interface individually for each coil. Thanks to it's design it can be mounted to most valves on the market.

Operational modes

The CJVD-10 valve driver has got three different operational modes:

  • On-off
  • Positive direction open-loop PWM
  • Negative direction open-loop PWM

Current monitoring is active in all operating modes.

CANopen® interface

The physical CAN interface in the CJVD-10 valve driver is according to ISO11898-2 High-speed CAN physical layer. Cost-optimised CANopen® interface is according to the following standards:

  • CiA® DSP 301 version 4.1.1
  • CiA® DR 303-1 version 1.4
  • CiA® WD 401 version 2.1.9


CJVD-10 valve driver has got open end cables, alternatively Bosch Compact style connectors for power supply and CAN.
Valve coil connector is 2-pole AMP Junior Power Timer.
