RM5800 Wireless HART

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 HART
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 HART

Key Features

specification. The RM5800 utilizes the global license-free 2.4GHz band at output power levels that are

TM

compatible communications.

Reliable Networking

• Mesh networking for redundancy and high reliability (> 99.9%

typical network reliability)

• Dynamic channel selection for interference rejection

• Every RM5800 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

• –95 dBm receiver sensitivity

• 300 m outdoor range (typical)

Data Security

• Uses AES FIPS PUB 197 (128 bit) encryption
