RM5800 Wireless HARTTM

2.4 GHz Radio Module

Product Description

Rosemount Inc.’s RM5800 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 RM5800 is designed to be fully compliant with the wireless HARTTM specification. The RM5800 utilizes the global license-free 2.4GHz band at output power levels that are compatible with government regulations throughout the world.

The RM5800’s very low power consumption characteristics make it perfect for battery powered equipment. The multi-functional interface of the RM5800 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 RM5800 is the best choice for wireless HARTTM compatible communications.

Key Features

Reliable Networking
