Smart Wireless THUM™ Adapter
The Smart Wireless THUM Adapter is used to wirelessly communicate HART® data acquired from a wired HART device using a self-organizing WirelessHART™ network.
The Smart Wireless THUM Adapter is:
- A device you can retrofit on any existing two or four-wire device
- Consists of a radio transmitter, receiver, microprocessor and antenna
- Allows you to wirelessly transmit HART measurement and diagnostic information that was previously not available

User selectable, 8 sec. to 60 min. |
|
| Electrical Connections |
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 volts at 3.5 mA to 1.2 volts at 25 mA, but does not effect the 4-20mA signal on the loop. Under fault conditions, the maximum voltage drop is 2.5 volts. |
| Power Supply |
Minimum load on loop 250 Ohms To maintain normal operating functions of the sub-device, the power in the loop must have at least a 2.5 V margin at a 250 Ohm load |
| HART Communicator Connections |
Utilize wired device HART connections |
| Materials of Construction |
| Enclosure |
Housing - Low-copper aluminum
Paint - Polyurethane |
| Antenna |
Poly butadine terephthalate (PBT) ⁄ Polycarbonate (PC) integrated omnidirectional antenna |
| Weight |
0.65 lbs (0.29 kg) |
| Enclosure Ratings |
Housing option code D is NEMA 4X, and IP66. |
| Mounting |
The THUM Adapter may be attached directly to the conduit of any 2- or 4-wire HART 5.0 device |
|
| ElectroMagnetic Compatibility (EMC) |
All Models: 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 0.15 mm displacement peak amplitude ⁄ 60-500 Hz 2g). When the THUM Adapter is used on wired devices that are subject to vibration levels greater than 2g, it is recommended that the THUM Adapter be remotely mounted. |
| Temperature Limits |
Operating Limit: -40 to 185 °F (-40 to 85 °C)
Storage Limit: -40 to 185 °F (-40 to 85 °C) |
| Noise level |
To ensure proper THUM adapter performance loop must conform with HART requirements for wired communication |
|
