The IFM CR3121 is an ISOBUS gateway designed to connect mobile-machine control systems with ISOBUS networks. It provides two CAN interfaces for communication between the machine controller and ISOBUS equipment. The ISOBUS interface operates according to ISO 11783 at 250 kBaud. A separate CAN interface supports CAN 2.0 A/B communication with configurable baud rates. Its IP67 housing and -40...80 °C operating range are suitable for demanding agricultural and mobile applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The CR3121 provides an interface between a CAN-based mobile controller and an ISOBUS network. The ISOBUS interface follows ISO 11783 and operates at 250 kBaud. This allows communication with compatible agricultural implements and vehicle systems. The gateway can transfer relevant data between the control system and ISOBUS network. It is therefore suitable for agricultural automation and implement communication.
A second CAN interface provides communication with the machine's control system. It supports CAN 2.0 A/B according to ISO 11898. The transmission rate can be configured between 125 and 1000 kBaud, with 250 kBaud specified in the product data. An integrated 120 Ω terminating resistor is provided on the CAN interface. This enables straightforward integration into CAN-based mobile-machine networks.
The CR3121 uses a compact black PA12 housing designed for mobile applications. Its IP67 protection rating provides protection against dust and water when correctly connected. The device operates from 12...27 V DC and has a current consumption of 11...48 mA according to the datasheet. An ARM Cortex M4 32-bit processor provides the processing platform. The device operates from -40...80 °C, making it suitable for demanding outdoor machinery.
