Abstract: In a modular data acquisition system (4), a module comprises at least one analog-to-digital converter (12) for converting an analog input signal (IN1, IN2, IN3, IN4) into a digital signal (OUT1, OUT2, OUT3, OUT4), and a clock generating circuit (20) for supplying an internal clock signal (209). The module further comprises a connector for plugging in a removable connecting element (3) on the front side of the module (1) in order to connect it to a synchronization bus connecting several modules in said system. A clock selecting circuit (204) enables the selection of either a slave-clock status, wherein the converters (12) are synchronized by an external synchronization signal supplied by said synchronization bus, or of a master-clock status, wherein the converters are synchronized by said internal clock signal which is also used a external synchronization signal on said synchronization bus. Trigger signals can also be transmitted by the synchronization bus and by the connecting elements.

Abstract: A data acquisition module (1) includes an interconnection board (15) with several electronic components (3, 18) mounted on at least one side of said board. A protective cover (16) mounted opposite said side covers the electronic components (3, 18). In order to cool notably the module's analog-to-digital converters, a piston 41 connected to the protective cover (16) is pressed by a spring (43) against the upper side of at least one electronic component (3) so as to establish a thermal bridge between said electronic component and said protective cover. The piston is mounted in a piston carrier fastened on the cover (16). The diameter of the portion (410) of the piston (41) that is in contact with the electronic component (3) to be cooled is smaller than the diameter of the portion (411) of the piston that is in contact with the piston carrier (40).
