Linking Computers with Industrial Networks
Fieldbus cards provide direct communication with systems such as CANbus, PROFIBUS, EtherCAT and Modbus. They allow industrial PCs to exchange data with controllers, sensors and machinery in real time.

Supporting Varied Protocols
Cards are available for both widely adopted and specialist fieldbus standards. This flexibility helps when building or maintaining mixed environments where different equipment must share information. Reliable communication reduces downtime and simplifies system integration.

Supplied Ready to Deploy
Each card is delivered with drivers and documentation to assist setup. They can be ordered alone or together with a full computer system to ensure complete compatibility. This makes it straightforward to add fieldbus capability to new projects or existing installations.
