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.

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.

Communication barrier arrangement and method for its operation

A module arrangement for a modular field device connection unit comprises a frame module having an interface receptacle, an interface module adapted to be inserted into the interface receptacle along a module insertion path, and a resetting mechanism adapted to reset the movable coding element into the neutral position by insertion of the interface module into the interface receptacle and/or removal of the interface module from the interface receptacle. The interface module has a cartridge receptacle and a movable coding element. The movable coding element is movable from a neutral position into a coding position by insertion of a cartridge member into the cartridge receptacle. The resetting mechanism has a trigger element at least partially protruding into the module insertion path.

An exemplary energy supply device for explosion-proof electronic functional units supplies each functional unit with a high-frequency AC voltage via an inductor. The inductors are formed as substantially congruent conductor tracks of a multi-level printed circuit board, which can be connected to one another and arranged vertically on a distribution printed circuit board. The number of metallization planes of the multi-level printed circuit board being greater than the number of metallization planes of the distribution printed circuit board.

Exemplary embodiments relates to a demodulator for frequency-shift keyed signals by using the Goertzel algorithm according to the general recursive calculating rule, where with the sampling frequency fand the specified frequency f. To reduce the mathematical complexity in feed-power-limited devices, it is proposed that the sampling frequency fis an integral multiple of the frequency fof a specified discrete spectral component.
