RELAY DELAY TURN-OFF CIRCUIT AND RELAY CONTROL METHOD

A relay delay turn-off circuit and a relay control method. The relay delay turn-off circuit includes a power control chip (1) outputting a first safety signal, a micro-control chip (2) outputting a second safety signal and a control group signal, a delay module (3), and a relay driving module (4). The delay module (3) receives the first safety signal, the second safety signal, and the control group signal, and outputs a first enable signal (EN1), a second enable signal (EN2), and a safety status signal. When the micro-control chip (2) resets, the first enable signal (EN1) delays a turn-off action of the relay driving module (4) until after a preset time, which is greater than a reset time. The power control chip (1) and the micro-control chip (2) output the first safety signal and the second safety signal according to their respective safety states.
