Claim 13:
14. The communication barrier arrangement according to claim 11, wherein the isolation barrier comprises a second transformer having a primary winding connected to the first driving stage and a secondary winding, where the second transformer is provided for transfer of second signals,
the second driving stage is connected to the secondary winding of the second transformer,
the second interface of the first signal conditioner is provided for receiving the second signals from the second process control system device destined for the first process control system device,
the second connection terminal of the first signal conditioner is provided for transmitting the second signals to the second driving stage,
the first connection terminal of the second driving stage is provided for reception of the second signals from the second process control system device, and
the first interface of the first driving stage is provided for delivering the second signals to the first process control system device,
further comprising a second capacitor connected in parallel with the primary winding of the second transformer, which second capacitor has a value selected to tune the resonance frequency of the second transformer to the carrier frequency.
