It integrates one RS232 port and two independent CAN bus ports, supporting diversified communication requirements and protocol conversion. This module can be seamlessly installed on CP260 CPU base plates and IF260/IF060 interface base plates, serving as a core expansion unit for building hybrid industrial communication networks. With compact mechanical structure, reliable circuit design and strong anti-interference capability, it is widely used in automated production lines, packaging machinery, textile equipment, industrial robots and power industry scenarios, and can adapt to complex on-site working conditions for long-term stable operation.

This module adopts a standardized plug-in structure exclusive to the B&R 2005 series, featuring small size and light weight to save cabinet installation space. Its overall dimensions are approximately 140mm in length and 80mm in width, and the net weight is about 0.1kg. It supports hot plugging and quick replacement, which greatly simplifies on-site maintenance and shortens equipment downtime. The product has passed CE, UL and CSA international safety and quality certifications, fully complying with global industrial electrical standards and applicable to industrial projects in various regions. It is equipped with a standard factory warranty to ensure stable and reliable operation throughout the service cycle. The module is a unified insertion unit for CPU and interface modules, and can be combined with base plates of different slot quantities to flexibly expand the system scale.

The 3IF672.9 is configured with one RS232 interface and two electrically isolated CAN bus interfaces, enabling multi-channel concurrent communication and flexible network topology layout. The RS232 interface is mainly used for program debugging, parameter configuration and point-to-point data transmission. Its maximum communication baud rate reaches 115.2 kBaud, with a standard transmission distance of 15 meters, and can be connected to serial sensors, human-machine interfaces and other serial devices. The dual CAN bus interfaces support a transmission rate of 500 Kbps and a maximum transmission distance of 1000 meters, which meets the long-distance communication needs of field buses. All communication interfaces are equipped with independent electrical isolation protection, which effectively isolates electrical interference and signal crosstalk between different channels and between the module and the main control system, and enhances communication stability in harsh industrial environments. This module is compatible with mainstream CAN bus and serial communication protocols, and can realize data interaction and interconnection between new B&R control systems and legacy field devices.

To facilitate real-time operation monitoring and rapid fault location, the module is equipped with dedicated LED status indicators. These indicators can clearly display the power-on state, data sending and receiving status of the RS232 channel and each CAN bus channel in real time. Operators can directly judge whether the communication link is normal through the light status, quickly locate faults such as signal interruption, transmission error and link abnormality, and carry out targeted troubleshooting. The intuitive indication design reduces the difficulty of daily operation and maintenance, and avoids prolonged production shutdown caused by hidden communication faults.

The module adopts a low power consumption design, with a rated power consumption of 2.0 W, which effectively reduces the overall energy consumption of the system and is suitable for large-scale multi-module combined layout. It has excellent environmental adaptability, with a continuous operating temperature range from -20°C to +60°C, and can work stably in high temperature, low temperature and temperature fluctuation environments. The protection grade reaches IP20, which can resist the intrusion of conventional dust in industrial sites and protect the internal circuit. It can adapt to a relative humidity of up to 95% in non-condensing conditions, and has strong tolerance to humid industrial environments, fully meeting the operation requirements of various complex industrial sites.

The 3IF672.9 adopts base plate plug-in installation and is compatible with the installation system of B&R 2005 series base plates. It can be directly inserted into the reserved slot of CP260 CPU base plate or IF260/IF060 interface base plate. The supporting base plates are available in multiple specifications with 6, 9, 12 and 15 slots, and users can select and match according to the actual number of modules and system expansion requirements. The base plates are installed on standard EN 50022 35mm mounting rails, with firm installation and neat wiring. In practical applications, this module is mainly used to expand the communication ports of PLC systems, connect PLCs with CAN bus drives, serial instruments and other field equipment, and build a unified integrated control network. It is widely applied in discrete manufacturing and process industries, helping users realize integrated control and efficient data transmission of the whole production system.
