Relay controller with generator of control instruction signal supplied to evaluator unit which, together with relay driver

摘要

Controller comprises control instruction generator (1) transmitting to relay (7) energising signal. To generator is coupled evaluator unit (3) for energising signal and for generating switching signal received by relay driver (4), which generates relay driver signal. Driver signal is supplied to relay over energising conductor (5), preferably surrounded by protection conductor (6). Evaluator unit and relay driver are parts of integrated circuit (2). INDEPENDENCE CLAIMS are included for method of relay control.
