Smart Wireless THUM™ Adapter
The optional Smart Wireless THUM adapter can be mounted directly on the transmitter or by
using a remote mounting kit. IEC 62591 (WirelessHART
®
) enables access to multi-variable data
and diagnostics, and adds wireless to almost any measurement point. See the Rosemount Smart
Wireless THUM Adapter Product Data Sheet (document number 00813-0100-4075) and Smart
Wireless THUM Adapter for Rosemount Process Level Transmitter Applications (document
number 00840-0100-4026).

External power supply
The input voltage UI for HART is 16-42.4 Vdc (16-30 Vdc in IS applications, and 20-42.4 Vdc in
Explosion-proof / flameproof applications).
