PURPOSE

This document serves as a user manual for the Emerson Rosemount RM5800 radio module.

GENERAL INFORMATION

PRODUCT DESCRIPTION
Rosemount Inc.’s RM5800 WirelessHART 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 WirelessHART 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 WirelessHART compatible communications.

ANTENNA SPECIFICATIONS

The antenna used with this module must meet the specifications below.

Parameter Value
Frequency range 2.4–2.4835 GHz
Antenna connector MMCX
Minimum cable length 100mm (3.937in)
Trace antenna specifications N/A

When the RM5800 is placed inside an enclosure, the antenna should be mounted such that the radiating portion of the antenna protrudes from the enclosure and connected using a coaxial cable. For optimum performance, allow the antenna to be positioned vertically when installed.
Note, local government regulations must be consulted with regards to approved antenna type and allowed antenna gain for use with this module.

INTEGRATION INSTRUCTIONS

DESIGN DESCRIPTION
The RM5800 connects to a host feature board via 22 pin connectors. Antennas or antenna adapter cables are connected to the radio module via MMCX cable connector.

INSTALLATION GUIDELINES
The RM5800 radio module is only available for use in the Emerson family of products. The RM5800 is not readily available to consumers; it is not sold by retail to the public. The RM5800 radio module has a limited modular approval, which requires that it be installed by approved host integrators under advisement of the module manufacturer. Host products are used in industrial and commercial environments.

REGULATORY AND STANDARDS COMPLIANCE

The RM5800 allows a limited modular host product implementation in the United States, Canada, and European Union. The following guidance must be reviewed to ensure final compliance to regulatory standards.
FCC COMPLIANCE TESTING
The RM5800 radio module has demonstrated compliance to FCC 15.247:2021.
To fulfill FCC certification requirements, products incorporating the RM5800 must comply with the following:

  1. An external label must be provided on the outside of the final product enclosure specifying the FCC identifier as described in 5.1.3 below.
  2. The antenna must be electrically identical to the FCC-approved antenna specifications for the RM5800 as described in 5.1.2 with the exception that the gain may be lower than specified in Section 5.1.2.
  3. The device integrating the RM5800 may not cause harmful interference, and must accept any interference received, including interference that may cause undesired operation.
  4. An unintentional radiator scan must be performed on each final device integrating the RM5800, per FCC rules and regulations, CFR Title 47, Part 15, Subpart B. If the final device system (host product and modular transmitter) exceeds the spurious emissions or output power limit, the product must not be marketed in the United States.
  5. Professional installation as per section 4.3 of the modular integration manual, available upon request.

Reference KDB 996369 D04 Module Integration Guide v02 for detailed integration and testing guidance.
FCC Antenna Selection
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter within a host device, except in accordance with FCC multi-transmitter product procedures.
Compliance to FCC rule 15.203 must be ensured in the final design of the product. Reference KDB 353028 for direct guidance on meeting this requirement. This can be done by either ensuring the professional installation of the final product or designing it in such a way as to make the antenna integral to the final product. Further, the RM5800 is only utilized by Emerson internal companies, and is not available to the general public. The RM5800 is an industrial network communication module and only works on Wireless Hart protocols and as such is part of an industrial process control system professionally installed and maintained per Section 4.3 of the modular integration manual, available upon request.
