Moxa CP-602U-I-T w/o cable; universal PCI board with isolation content_copy

The Moxa CP-602U-I-T is an industrial-grade CAN interface card with two independent ports, designed for use in automation systems and data acquisition environments. As a PCI card in Universal PCI format (32-bit, compatible with 3.3 V and 5 V slots), it enables integration of CAN-based devices into existing PC systems. The card supports CAN protocols 2.0A and 2.0B and is designed for operation in demanding industrial environments, with the -T variant offering an extended temperature range of -40 to +85 °C.

Applications
The card is suitable for applications requiring reliable communication over CAN bus systems, such as in manufacturing automation, vehicle technology, power supply, or process control. The electrical isolation of 2 kV per port protects the card and the host computer from voltage spikes and potential differences, which is particularly important in electrically harsh environments. The integrated LED indicators for transmission (Tx) and reception (Rx) per port facilitate visual monitoring of communication activities.

Functions and Features in DetailEach of the two CAN ports supports a baud rate of up to 1 Mbps, with the speed configurable in steps of 10, 20, 50, 125, 250, 500, 800, and 1000 kbps. Communication is enabled by the NXP SJA1000 CAN controller and the PCA82C251 transceiver, which together ensure bus arbitration, error detection, and robust data transmission. An optionally switchable 120-ohm termination resistor per port supports correct signal transmission in CAN bus networks and simplifies integration into existing systems.

Technology Explained SimplyThe card uses the Universal PCI standard, supporting both 3.3 V and 5 V PCI slots, enabling broad compatibility with various industrial PCs. The electrical isolation of 2 kV protects internal circuits from transient voltages caused by electrical discharges or power line disturbances. The DB9 connectors (male) per port provide a standardized physical interface for CAN cables. Software support includes drivers for Windows systems and a DLL library with sample code, simplifying application development.

Compatibility and AccessoriesThe card is designed for use in systems with Universal PCI slots. The CAN protocol support 2.0A and 2.0B enables communication with a wide range of CAN devices. The certifications according to EN 55032/35, CISPR 32, and FCC Part 15B Class B ensure good electromagnetic compatibility. The EMS certifications according to IEC 61000-4-2 to -4-11 guarantee functionality under various electromagnetic interference conditions, including ESD (4 kV contact, 8 kV air), EFT (1 kV on power supply, 0.5 kV on signals), and Surge (2 kV). The RoHS, CRoHS, and WEEE compliance meets environmental requirements.

Installation and MountingInstallation is performed by inserting the card into a free Universal PCI slot of the host computer. Physical mounting requires no additional tools, as the card is fixed directly in the slot. Configuration is done via the provided drivers and DLL library, with baud rate and termination resistor adjustable via software or hardware switches.

Operational AdvantagesThe card offers a cost-effective and robust solution for CAN communication in industrial applications. The 2 kV isolation enhances safety and component lifespan. The extended operating temperature range of -40 to +85 °C enables use in extreme environments, such as outdoor installations or vehicles. The visual status indication via LEDs simplifies troubleshooting and maintenance. The 5-year warranty underscores the product's reliability.

The card is designed for use in industrial environments with high requirements for electromagnetic compatibility, temperature resistance, and mechanical robustness. The Universal PCI compatibility ensures broad applicability across various systems. The CAN protocol support 2.0A/2.0B enables interoperability with a wide range of devices and systems.
