The external inputs have a built in hardware noise filter for improved compliance with electromagnetic emission requirements. The input filter introduces a delay in the input response time. The delay times are different for OFF and ON, and vary with the supply voltage. Turn-on time is less than 1µS. Turn-off time is approximately 500µS divided by the supply voltage, i.e. 42µS at 12V and 21µS at 24V.
