Creating a mathematical model of a universal electromagnetic dc relay in the software Matlab

Bagryantsev Ilya Andreevich, Belenov Daniil Andreevich

The article presents a model of a universal DC electromagnetic relay developed in the Matlab software product, which allows you to choose both the principle of operation of an electromagnet (on reaching a predetermined voltage, current or time value) and the response time of the contact group (without delay, with a turn-on delay, with switch-off delay or switch-on and switch-off delay). The DC electromagnetic relay block outputs logic levels for the operation of power switches - normally open contacts and normally closed ones. The number of contacts connected to the relay is not limited, and the convenient and intuitive mask of the developed block allows you to easily use this relay in the development and testing of relay-contactor circuits.
