The present invention relates to a device (100) for operation in a network (400), wherein the device (100) comprises a sensor, an
actuator, a
transmitter and / or
receiver unit, or other
electronic equipment, wherein the network is configured as a two-wire network with
Power over Dataline (PoDL), comprising at least one first input-side interface (102), at least one second output-side interface (104), a
power supply unit (110), a functional unit (180), and a data and electronic
assembly (190), wherein the data and electronic
assembly (190) comprises the following: a processor unit (170), an input-side
PHY (172), an output-side
PHY (174), an input-side
coupling unit (176), and an output-side
coupling unit (178), wherein the first interface (102) is connected to the second interface (104) via a two-wire
feedthrough line. (120) is connected,which has a first conductor (122) and a second conductor (124), - wherein the
power supply unit (110) is connected to the two-wire through-line (120) via a first input-side node pair (132, 134) and a line
branch (140), and - wherein the data and
electronic component (190) is arranged parallel to the through-line (120) via a node pair (136, 138) in the line
branch (140) leading to the
power supply unit (110) and via an output-side line (150) and a second output-side node pair (132, 134), characterized in that - at least one first differential-mode
choke (160) is arranged as a low-pass filter in the line
branch (140) between the node pair (136, 138) and the power supply unit (110), and - in the through-line (120) A second push-pull
choke (130) is arranged as a low-pass filter between the first input-side node pair (132, 134) and the second output-side node pair (132, 134).
