<p>The interface device comprises a base (28) on which are mounted interface modules (39a, 39b, 39c). The base incorporates windows (31a-31f) arranged in rows and columns, and the modules have a width corresponding to a whole number of columns. Common leads (34a, 34b, 34c, 34d) are each common to one of the rows of windows. The modules (39a-39c) comprise contact clips for said common conductors to provide connection with the 'processing' and 'installation' electrical sources through the terminals (35) provided on a power supply block (36) integral with the base (28) and carrying also a push button (44) for unlocking the modules. Each module carries also a terminal (25) for connection with the signal terminal of the logic controller and two or four terminals (24) for connection with the installation. Useful for facilitating assembly and wiring with a low cost material offering a wide freedom in the choice of circuits.</p> |
