Abstract: A communication barrier arrangement includes a first driver having a first interface for receiving signals from a first device destined for a second device, an isolation barrier including a first transformer for signal transfer and having a primary winding connected to the first driver and a secondary winding, a second driver connected to the secondary winding and having a first connection terminal for output of the signals towards the second device, a first signal conditioner having a second connection terminal for receiving the signals from the second driver and a second interface for delivering them to the second device and a protection circuit including a resistor in parallel with a first capacitor, the protection circuit being connected between the first and second connection terminals.

Abstract: A terminal block unit for an input/output device of a modular process control system includes two slot elements configured to receive two redundant signal conditioning units. The terminal block unit is configured to be housed in a pair of two adjacent slot elements of a module termination unit of an input/output device. The terminal block unit provides a parallel connection of the redundant signal conditioning units to a field device.
