Abstract

The invention relates to a module for measuring purposes comprising an electrical or electronic circuit, which has at least one power supply connection and at least one data line connection for connecting, in the manner of a bus, to at least one other module of the same type that is also used for measuring purposes. According to the invention, the electronic circuit (80) is arranged inside a housing, the housing has a first contact surface (90) and a second contact surface (91), and the first contact surface (90) is joined to the second contact surface (91) of the other module (22, 32, 42) in a manner that permits it to be mechanically detached. The at least one power supply connection has a power supply contact (84a, 85a) in the first contact surface (90) and has a corresponding power supply contact (84b, 85b) in the second contact surface (91). The at least one data line connection has a data line contact (86a, 87a) in the first contact surface (90) and has a corresponding data line contact (86b, 87b) in the second contact surface (91). When the first contact surface (90) is joined to the second contact surface (91) of the other module (22, 32, 42), the power supply contact (84a,…
