An automation device configured for use in an automation environment for automation of an industrial process includes an enclosure and a printed circuit board arranged parallel to first and second side parts at right angles to an upper or underside of the enclosure, wherein the printed circuit board carries a microprocessor in thermal connection with a heat sink that has cooling metal sheets, where the heat sink has a plurality of cooling metal sheets each arranged parallel to the printed circuit board with a clearance between them such that, for a first installation position in which the underside is aligned horizontally, a cooling medium flows from the underside through clearances, and where openings are each arranged in the cooling metal sheets such that, for a second installation position in which the underside is aligned vertically, the cooling medium flows through the openings arranged one above the other.

A field device for use in an industrial process includes a housing having a cavity formed therein. A humidity-sealed electronics module has a first compartment formed therein and is positioned in the cavity. The humidity-sealed electronics module includes a seal board. The seal board separates the first compartment of the humidity sealed electronics module from a second compartment in the housing. A first electrical component in the first compartment is mounted to the seal board and a second electrical component in the second compartment is electrically connected to the first electrical component.

A transmitter housing of an automation field device is a single-chamber housing with an aperture. The field device comprises a printed circuit board arranged in the transmitter housing, the printed circuit board comprising: a first rigid and flat section and a second rigid and flat section; at least one flexible and bent section; wherein both rigid sections are connected to each other only via the at least one flexible, bent section, wherein the first rigid section is accessible from the aperture and forms a connecting region comprising at least one connecting element for connecting at least one cable, and wherein the first rigid section and the second rigid section are arranged relative to each other at a first angle of between 60 and 120, in particular between 80 and 100.

An electronic device having a housing for accommodating electronic components, preferably electronic components forming a process transmitter. The housing has two chambers, in which electronic components and user interfaces and/or connection elements for cable are arranged. The electronic components are arranged in a first chamber. In the case of a process transmitter, which is simple to maintain, electronic components are arranged exclusively in the first chamber, while user interfaces of the electronic components and/or connection elements for cable are positioned exclusively in the second chamber.

A field device of automation technology includes: a field device housing; a field device electronics unit having at least one circuit board; a circuit board holder arranged in the housing for holding the circuit board, wherein the circuit board holder has an engagement mechanism for resistance fastening of the circuit board, wherein the circuit board has at least one counter-engagement mechanism corresponding to the engagement mechanism, wherein the engagement mechanism is a latch formed from the wall or provided in the wall, wherein the latch is flexibly embodied such that, in a non-engaged state, the latch extends out from the outer contour of the wall of the circuit board holder, and, in an engaged state, the latch has moved in the direction of the at least one circuit board as to be engaged with the counter-engagement mechanism.
