IEC 62591 (WirelessHART®)... the Industry Standard

Self-organizing, adaptive mesh routing

 No wireless expertise required. Devices automatically find the

best communication paths.

 Network continuously monitors paths for degradation and

repairs itself.

 Adaptive behavior provides reliable, hands-off operation and

simplifies network deployments, expansion, and
reconfiguration.

 Supports both star and mesh topologies.

Industry standard radio with channel hopping

 Standard IEEE 802.15.4 radios

 2.4 GHz ISM band sliced into 16 radio channels

 Continually “hop” across channels to avoid interference and

increase reliability

 Direct sequence spread spectrum (DSSS) technology delivers

high reliability in challenging radio environment

Self-healing network

 The self-organizing, self-healing network manages multiple

communication paths for any given device. If an obstruction is
introduced into the network, data will continue to flow
because the device already has other established paths. The
network will then lay in more communication paths as needed
for that device.

Seamless integration to existing hosts

 Transparent and seamless integration

 Same control system applications

 Gateways connect using industry protocols

Physical specifications

Material selection

Emerson provides a variety of Rosemount product with various
product options and configurations including materials of
construction that can be expected to perform well in a wide
range of applications. The Rosemount product information
presented is intended as a guide for the purchaser to make an
appropriate selection for the application. It is the purchaser’s
sole responsibility to make a careful analysis of all process
parameters (such as all chemical components, temperature,
pressure, flow rate, abrasives, contaminants, etc.), when
specifying product, materials, options and components for the
particular application. Emerson is not in a position to evaluate or
guarantee the compatibility of the process fluid or other process
parameters with the product, options, configuration or
materials of construction selected.

Electrical connections

The THUM Adapter is connected into a powered 4–20 mA loop,
powering itself by scavenging power. The THUM Adapter causes
a voltage drop across the loop. The drop is linear from 2.25 V at

3.5 mA to 1.2 V at 25 mA, but does not effect the 4–20 mA
signal on the loop. Under fault conditions, the maximum voltage
drop is 2.5 V.

Power supply

Minimum load on loop 250 Ohms

To maintain normal operating functions of the sub-device, the
power in the loop must have at least a 2.5 V margin at a 250 Ω
load.

Limit power supply to 0.5 Amps maximum.

Limit power supply to 55 Vdc maximum.
