VEGA WHA-ADP-F8B2 User Manual

WirelessHART Adapter

WHA-ADP-F8B2-*-P*-Z2(-1)

Features

• 1-channel

• WirelessHART Adapter

• Battery operated

• Also supplies field device

• Input 2-wire HART transmitters and 2-wire HART current
sources

• Output WirelessHART wireless interface

• Direct mounting on HART- or 4 mA ... 20 mA field device

• Rotatable antenna

Function

The device upgrades a conventional HART or 4 mA ... 20 mA
field device with a WirelessHART interface. It is mounted
either directly to the cable gland entry or separated from the
field device.

The device contains a battery pack which also powers the
field device. Depending on the parameterization, battery
lifetimes up to 5 years are possible. This allows autonomous
measurements. The rotatable antenna can be brought in the
optimal position, regardless of the mounting orientation of the
field device.

The unit is easily programmed with a configuration tool (DTM
or DD).
