Confidential RM2510 Datasheet Rosemount Inc. 1 RM2510 Wireless HARTTM 2.4 GHz Radio Module Product Description Rosemount Inc.’s RM2510 Wireless HARTTM 2.4GHz Radio Module has been specifically designed to interface with industrial and process control equipment designed and marketed by the Emerson family of companies. The RM2510 is designed to be fully compliant with the wireless HARTTM specification. It uses a DSSS modulation type and multiple channel selection for optimum interference rejection and >99% communication reliability. The RM2510 utilizes the global license-free 2.4GHz band at output power levels that are compatible with government regulations throughout the world. The RM2510’s very low power consumption characteristics make it perfect for battery powered equipment. The multi-functional interface of the RM2510 is flexible enough for it to be integrated into many types of sensors. From pressure, temperature, and flow monitoring to machinery health and valve position control, the RM2510 is the best choice for wireless HARTTM compatible communications. Key Features Reliable Networking • Mesh networking for redundancy and high reliability (> 99.9% typical network reliability) • Dynamic channel selection for interference rejection • Every RM2510 acts as both an endpoint and a router, increasing network reliability. • Automatic self-organizing mesh-networking capability built-in Easy Integration • Well-defined multi-functional interfaces • High-level Data Link Control (HDLC) serial interface with bidirectional flow control • Industrial temperature range –40 °C to +85 °C 802.15.4 Standard Radio • +8 dBm (6.3 mW) conducted RF output power • –90 dBm receiver sensitivity • 300 m outdoor range (typical)
