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.

When the RM2510 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.

7.0 Regulatory and Standards Compliance
The RM2510 has achieved modular radio certification on a reference design for the United States, Canada and the Europe. The reference design
has been certified for Part 15.247 (Intentional Radiator) of the FCC rules an regulations, Industry Canada RSS-210, ETSI EN 300 328 and ETSI
EN 301-489-17.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
The RM2510 complies with Part 15.247 modular (Intentional Radiator) FCC rules and regulations. Changes or
modifications not expressly approved by Rosemount Inc. could void the user's authority to operate the equipment.
7.1 FCC Testing
In order to fulfill FCC certification requirements, products incorporating the RM2510 must comply with the following:

described in 7.3 below.
2. The antenna must be electrically identical to the FCC-approved antenna specifications for the RM2510 as described in
7.2 with the exception that the gain may be lower than specified in Table 14.
3. The device integrating the RM2510 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 the device integrating the RM2510, per FCC rules and
regulations, CFR Title 47, Part 15, Subpart B. See FCC rules for specifics on requirements for declaration of conformity.
7.2 FCC-approved Antenna
The FCC-approved antenna specifications for the RM2510 is an antenna with a Maximum gain of +2dBi, vertical polarization, and
