APPROVAL OF THE ELECTRICAL PARAMETERS OF SIGNAL SOURCES AND INPUT MODULES PROGRAMMABLE CONTROLLERS
The article noted the need to harmonize the electrical parameters of the sensors of digital signals (switches, buttons, and travel limit switches, relay contacts, etc.) and input modules programmable logic controllers (PLCs), which are widely used in modern systems of technological equipment. Matching parameters are the currents and voltage sensors and input modules. The necessity of the conditions under which ensures the accuracy of distinguishing states sensors formed of signals and reliable operation of the control system. Showing the practical options for these conditions are met. A new method for matching the parameters of signal sources (sensors) and the PLC input modules and marked features of its implementation. Articulate the benefits of practical application of the proposed method recognized by the present invention.
