[Elecraft] [K3S] "Hardware Sequencer" WSJT-X?

[MaverickNH]

As in WSJT-X 1.70 online help:  "Set Tx delay to a number larger than the
default 0.2 s to create a larger delay between execution of a command to
enable PTT and onset of Tx audio.

For the health of your T/R relays and external preamplifier, we strongly
recommend using a hardware sequencer and testing to make sure that
sequencing is correct."

What would this "hardware sequencer" and need I be concerned with a K3S?
