the THUM adapter is a Smart Wireless Gateway and a new or existing Rosemount magnetic transmitter. All of Emerson’s Smart Wireless field network devices can be integrated directly into your existing automation architecture without the need for upfront engineering, site surveys or additional software. Wired or wireless the network looks the, Smart Wireless THUM Adapter CONSIDERATIONS General The Smart Wireless THUM Adapter is co nnected to a HART sub-device. With simple HART configuration, the THUM transmits the HART information from the sub-device into the Wireless network.
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, Smart Wireless THUM Adapter April 2010 2 Wireless Overview SELF-ORGANIZING NETWORKS The self-forming, intelligent devices provide exceptional data reliability and network stability. The Smart Wireless THUM Adapter works with existing wired devices, allowing you to use existing practices, training and maintenance procedures, without the, Page 12 Reference Manual 00809-0100-0775, Rev AA March 2009 Smart Wireless THUM Adapter The THUM can be installed in one of two configurations: Direct Mount, where the THUM is Mounting connected directly to the conduit entry of the sub-device, or Remote Mount, where the THUM is mounted separate from the sub-device housing, then connected to the sub-device via conduit.
