RM2510 Wireless HART
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 HART
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 HART
