Specifications
Functional Specifications
Input
Any 2‐ or 4‐wire HART 5.0 powered device
Output
WirelessHART Communication Protocol
Humidity Limits
0-100% relative humidity
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
loop.
Power Requirements
SmartPowert: Power scavenging technology (no battery
required)
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.

Mounting
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.
Mounting Connection: 1/2 NPT external
Dimensions
Performance Specifications
ElectroMagnetic Compatibility (EMC)
Meets all relevant requirements of EN 61326‐1 (2006)
when installed with shielded wiring. The sub‐device must
also use shielded wiring for installation.
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
mounted.
