CANopen DIN-A valve driver is 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 its design it can be mounted to most valves on the market.

Operational modes

The CANopen DIN-A valve 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 DIN-A valve driver is according to ISO 11898-2 high-speed CAN physical layer. Cost-optimized CANopen interface is according to the following standards:

• CiA 301 version 4.1.1
• CiA 303-1 version 1.4
• CiA 401 version 2.1.9

Connectors

CANopen DIN-A valve has got Bosch Compact type dual connector for power supply and CAN. Valve coil connector is 2-pole DIN 43650-A/ISO 4400.
