The IFM CR3146 is a CAN LTE/GNSS radio modem designed as a 4G mobile IoT gateway for connected mobile machines. It combines cellular communication, GNSS positioning, CAN communication and an additional digital output. The integrated cellular modem supports GSM, GPRS, EDGE, UMTS, HSPA, 3G and 4G LTE Cat-4 technologies. GNSS functionality supports location-related machine applications. Its IP67 housing and -40...85 °C operating range make it suitable for demanding mobile environments.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The CR3146 provides cellular connectivity between a mobile machine and remote IoT or cloud systems. It supports 4G LTE Cat-4 as well as earlier cellular technologies for broader network compatibility. The integrated SIM and antenna arrangement simplifies installation. Machine information can be transmitted through the mobile network to remote applications. This allows equipment operators to monitor machines without requiring a local wireless network. It is suitable for fleet management and connected-machine applications.
Integrated GNSS functionality provides positioning information for mobile equipment. The device can be used for location tracking and fleet-monitoring applications. It also includes acceleration measurement with three axes and a ±16 g measurement range. Vehicle inclination and yaw-rate measurement functions are also provided. These measurement capabilities can provide additional information about machine movement. Such data can be useful for advanced telematics and machine monitoring systems.
The CR3146 includes a CAN interface for communication with the machine control network. CAN 2.0 A/B according to ISO 11898 is supported. A digital output provides an additional machine interface with a 500 mA permanent current rating. The device operates from 6...36 V DC and includes an integrated USB interface for firmware updates. IP67 protection and -40...85 °C operation make it suitable for harsh mobile-machine conditions.
