Abstract

A circuitry for processing analogical current and voltage signals to be further processed by microcomputers (4, 5) has at least two input modules (1) for processing voltage signals and at least two input modules (2) for processing current signals. Among these modules, at least one input module (1, 2) of each type is coupled by two constant current sources (3) to two microcomputers (4, 5). Two detachable connections (6, 7) arranged at the output of each of the other input modules (1, 2) make it possible to connect at least one input module (1, 2) to both microcomputers (4, 5), via two constant current sources (3), or to connect at least one input module (1) for voltage signals to one microcomputer (4) and at least one input module (2) for current signals to the other microcomputer (5), each time via a constant current source (3). The number of inputs of both microcomputers (4, 5) is the same and always smaller than that of the input modules (1, 2). The number of constant current sources (3) corresponds to the sum of the inputs of both microcomputers (4, 5). The advantage of this circuitry lies in the possibility to match the fixed and variable input modules (1, 2) so that the greatest possible freedom is ensured at the design stage with a minimal amount of hardware.
