Sensor IQ Built in Relay Delay / Phased Turn On

Issue

When I turn all of my relays on or off at the same time, there is a slight delay between each of the relays getting to their new state.

Explanation of Issue

SensorIQ has a built in delay to reduce inrush current and nuisance tripping. Sensor IQ switches a maximum of 3 relays per operation for each side of the cabinet (i.e. 3 on the left and 3 on the right max). This phasing occurs regardless of control input (Set Levels, DMX, or sACN).
