The automation module comprises a high voltage region (6) and a low voltage region (4). It additionally comprises an insulation region (5) for separating said high (6) and low (4) voltage regions, a first circuit board (41, 41′) having at least one input interface (411, 414), a second circuit board (42) having at least one control unit (422), and a third circuit board (61) having at least one switching element (611). Said first, second and third circuit boards (41, 41′; 42, 61) and the insulation region (5) are arranged one above the other in layers. ## Claims ### Claim 1 An automation module for building automation, which is designed for at least partial flush-mounted installation in a wall of a house, having a high-voltage region and a low-voltage region and comprising an insulation region for separating the high-voltage region from the low-voltage region; a first printed circuit board having at least one input interface; a second printed circuit board having at least one control unit; and a third printed circuit board having at least one switching element; wherein the first, second and third printed circuit boards and the insulation region are arranged above one another in layers. ### Claim 2 (depends on 1) The automation module as claimed in claim 1, wherein the insulation region is arranged between the second and third printed circuit boards. ### Claim 3 (depends on 2) The automation module as claimed in claim 2, wherein the second and third printed circuit boards each comprise electronic components, and wherein these electronic components are largely arranged on those sides of the second and third printed circuit boards which are opposite to the insulation region. ### Claim 4 (depends on 1) The automation module as claimed in claim 1, wherein a current sensor is mounted on the first or second printed circuit board. ### Claim 5 (depends on 1) The automation module as claimed in claim 1, wherein at least one of at least one service and programming interface is provided on the second printed circuit board, and wherein the first printed circuit board comprises at least one continuous access opening which allows access to at least one of the service and programming interface. ### Claim 6 (depends on 1) The automation module as claimed in claim 1, wherein the first, second and third printed circuit boards are each connected to one another by means of accordingly provided electrical plug connections. ### Claim 7 (depends on 6) The automation module as claimed in claim 6, wherein the first, second and third printed circuit boards can each be separated from one another in a non-destructive manner by releasing the electrical plug connections. ### Claim 8 (depends on 1) The automation module as claimed in claim 1, wherein a connection for a data bus which is used to network a plurality of automation modules is provided on the first, second or third printed circuit board. ### Claim 9 (depends on 1) The automation module as claimed in claim 1, wherein the first, second and third printed circuit boards each have substantially an octagonal form. ### Claim 10 (depends on 1) The automation module as claimed in claim 1, wherein a housing having a continuous housing opening laterally surrounds the first, second and third printed circuit boards. ### Claim 11 (depends on 1) The automation module as claimed in claim 1, wherein the third printed circuit board has a larger diameter than the first and second printed circuit boards. ### Claim 12 (depends on 11) The automation module as claimed in claim 11, wherein the housing comprises, in the region of the third printed circuit board, a groove which extends on an inner side of the housing along a circumferential direction of the housing, and wherein the groove is used to accommodate the third printed circuit board. ### Claim 13 (depends on 1) A building automation apparatus comprising at least one automation module as claimed in claim 1. ### Claim 14 (depends on 4) The automation module as claimed in claim 4, wherein the current sensor is an inductive current sensor. ### Claim 15 (depends on 4) The automation module as claimed in claim 4, wherein the insulation region comprises an insulation plate having a cutout through which the current sensor projects. ### Claim 16 (depends on 8) The automation module as claimed in claim 8, wherein the connection for a data bus is provided on the first printed circuit board. ### Claim 17 (depends on 10) The automation module as claimed in claim 10, wherein the housing has an octagonal form.
