775 Smart Wireless THUMt Adapter
The Smart Wireless THUM adapter is a device for use
on HARTr communicating instruments such as the
Fisherr FIELDVUEt digital valve controller. The THUM
adapter adapts the wired HART protocol to the
WirelessHARTr protocol.
n Loop Powered—No batteries; power scavenging
technology. No maintenance required.
n Reliable Wireless—The WirelessHART
In many process facilities, HART communicating field
devices have been installed and working for years.
However, getting important information such as valve
health to the people who need it is a challenge, as
diagnostic information is often inaccessible.
communication protocol provides the high level of
communication reliability required in process
control applications.
n Rugged Construction—The electronics are fully
encapsulated and enclosed in an aluminum
n Security—The WirelessHART self‐organizing mesh
A wireless network can be deployed to gain access to
valve diagnostics. The THUM adapter is installed on
field devices one at a time - significantly reducing the
risk and impact of installation error. Plus, the network
is scalable. Start with one THUM adapter on a
FIELDVUE digital valve controller. Then, as you see the
value it brings, add more devices to the network.
network includes encryption, authentication, and
authorization mechanisms to provide industry
leading security.
n Wireless Connectivity—The THUM adapter enables
configuration, calibration, and valve health
monitoring via AMS.
n Installation Flexability—The THUM adapter can be
installed anywhere along the control wires.

Functional Specifications
NEMA 4X and IP66
Any 2‐ or 4‐wire HART 5.0 powered device
May be installed anywhere on the control wiring loop.
Typically, mounting will be on or near the control valve.
May be mounted directly on the available conduit opening
of the terminal box or remotely using remote mount kit.

Burst Rate
User selectable, 8 sec. to 60 min.
Physical Specifications
Electrical Connections
The THUM adapter is connected in series with the 4-20 mA
Power Requirements
SmartPowert: Power scavenging technology (no battery
The THUM adapter draws power by drawing voltage from
the loop. The drop is linear from 2.25 volts at 3.5 mA to 1.2
volts at 25 mA, but does not affect the 4-20 mA current
signal. Under fault conditions, the maximum voltage drop
is 2.5 volts.

Vibration Effect
Output unaffected when tested per the requirements of
IEC60770‐1 field with general application or pipeline with
low vibration level (10-60 Hz 0.15mm displacement peak
amplitude / 60-500 Hz 2g).
When the THUM adapter is used on wired devices that are
subject to vibration levels greater than 2 g, it is
recommended that the THUM adapter be remotely
