Rosemount 5300 Series
October 2014
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
(1)
The input voltage (U
I
) for HART is 16-42.4 Vdc
(16-30 Vdc in IS applications, and 20-42.4 Vdc in
Explosion-proof / Flameproof applications). For
installations with high transients, an IS
transmitter should be used.
For Flameproof/Explosion-proof installations the
Rosemount 5300 Series transmitters have a
built-in barrier; no external barrier needed.
(2)
When a Smart Wireless THUM Adapter is fitted, it
adds a maximum drop of 2.5 Vdc in the
connected loop.
