The Moxa CB-602I is a 2-port CAN-bus module in PC/104-Plus format, specifically developed for use in industrial environments with high requirements for reliability and robustness. It is designed for communication over CAN-bus networks and enables the integration of CAN-capable devices into embedded systems based on the PC/104-Plus bus. The module supports CAN 2.0A and CAN 2.0B standards and offers a maximum transmission rate of up to 1 Mbps, making it suitable for applications requiring high data rates. The electrical isolation of 2 kV protects the module and connected systems from voltage spikes and potential differences.

Applications

The CB-602I is designed for use in harsh industrial environments, such as manufacturing automation, power supply, transportation, or mobile machinery. It is suitable for systems requiring reliable, interference-free communication over CAN-bus, particularly in environments with electromagnetic interference or mechanical stress. The availability of a version with an extended temperature range (CB-602I-T) expands its use to extreme climatic conditions, such as outdoor installations or vehicles.

Features and Equipment in Detail

The module features two independent CAN ports, each connected via a 20-pin box header. Each port is equipped with integrated LED indicators for transmission (Tx) and reception (Rx) to visually monitor communication status. Communication is handled by the NXP SJA1000 CAN controller in combination with the PCA82C251 transceiver, ensuring efficient bus arbitration and error detection. Optional integrated 120-Ohm termination resistors support signal integrity in the CAN-bus network and prevent reflections.

Technology Explained Simply

The CAN interface enables serial communication between multiple devices in a network, with data prioritization managed via a token-based mechanism. The maximum baud rate of 1 Mbps enables fast data transfer, which is important for time-critical applications. The 2 kV electrical isolation protects the module and connected systems from voltage spikes caused by electrical interference or potential differences. Support for CAN 2.0A and CAN 2.0B ensures compatibility with a wide range of CAN devices.

Compatibility and Accessories

The CB-602I is designed for use in the PC/104-Plus bus (PCI) and can be integrated into systems with up to eight boards per PC. Software support includes Windows drivers, a DLL library, and programming examples to facilitate integration into application software. The model variants differ in operating temperature: the standard model is designed for 0 to 55 °C, while the CB-602I-T version covers the extended range of -40 to 85 °C.

Installation and Mounting

The module is installed into a PC/104-Plus system, with mechanical mounting via standard plug connections. Connections to CAN-bus networks are made via the 20-pin box headers. Installation requires no additional tools or components, as the module is directly integrated into the system. Software integration is achieved using the provided drivers and libraries.

Operational Advantages

The combination of high isolation strength, robust design, and support for CAN 2.0A/B makes the CB-602I a reliable communication module for industrial applications. The LED indicators enable quick diagnosis of communication issues. Support for multiple baud rates (10, 20, 50, 125, 250, 500, 800, 1000 kbps) provides flexibility in network configuration. The warranty is 5 years, highlighting the product’s durability and reliability.
