CAN in industrial automation

The multi-layer structure of Controller Area Network (CAN) allows any station on a serial bus to communicate with any other station. There are also benefits in central control and self-diagnosis and correction of transmission errors.

A number of CAN-based higher level protocols have been developed for use in industrial automation applications.

CAN Application Layer (CAL), CAN Kingdom, CAN-open, DeviceNet and Smart Distributed System are just a few of these variations.

CAN isolator boosts signal,
increases number of nodes.

• Extend the node capacity of your CAN network
• Optical isolation to 2000 VDC. Stops surges and spikes
• DIN rail mount
• Terminal block connections

Optical isolation stops surges Model CANOP extends the node capacity of your CAN systems and protects your CAN network from component killing surges and transients. Model CANOP is an optically isolated CAN repeater that provides 2000 VDC of optical isolation, allowing you to separate and protect critical segments of your system from the rest of the CAN network.

Send CAN signals over fiber for noise resistance and isolation

• Convert CAN signals to fiber and fiber to CAN
• Fiber is naturally resistant to surges, spikes and electrical noise
• DIN rail mount
• Terminal block connections for copper
• ST connectors for fiber

Fiber optic cable offers natural resistance to EMI/RFI noise and surges that commonly interfere with electrical networks on factory floors and in industrial environments. Model CANFB converts CAN signals from copper to fiber and from fiber to copper. To connect two CAN devices with fiber optic cable, two Model CANFB converters are required. Copper connections are terminal block. Fiber connectors are standard ST connectors.
