Dual relay switching delay module
Version 2 - Last update: Jun 30, 2016

One input, two lowside outputs. RC circuit delays input to two comparitors set at different levels. One output turns on before the other and vice versa.

Circuit is used to control two lowside outputs. One output turns on before the other. The same output turns off after the other. An RC circuit is used to set the delay time and a dual comparitor sets the levels at which the outputs are enabled.
