A field device adapter for wireless data transfer, comprises at least: an adapter housing; an adapter electronics unit arranged in the adapter housing, the adapter electronics unit comprising a first supply circuit, which is introduced into the first connection line, for providing a first supply voltage from a loop current flowing in the first connection line, and a second supply circuit, which is introduced into the second connection line, for providing a second supply voltage from the loop current flowing in the second connection line, wherein the adapter electronics unit further comprises a HART modem and a wireless module with an antenna for transmitting and/or receiving, and the adapter electronics unit is configured such that the first supply circuit supplies the HART modem with the first supply voltage, and the second supply circuit supplies the wireless module with the second supply voltage.

Disclosed is a field device adapter for wireless data transfer, comprising: an adapter housing having a first and a second end, the first end such that the field device adapter can be mechanically connected to a field device and the second end such that a two-wire cable can be connected to the field device adapter. The adapter housing also having an adapter chamber; a supply electronics unit arranged in the adapter chamber and designed to provide a supply voltage via a voltage tap; an adapter electronics unit; and an adapter connection cable at the first end for connecting the adapter electronics to a field device electronics. The adapter electronics are designed to communicate the two-conductor signals between the field device electronics and the two-conducting-wire cable and also to convert the two-conductor signals into radio signals or vice versa.
