After the previous channel relay is opened, the selected channel relay is closed (break before
make).
Channel switching cannot be overlapped (make before break).
In channel switching within the same slot, the bus relay is not opened and only the channel relay is
switched.
If the channel for a different slot is selected, the bus relay and channel relay of the previous slot are
opened and the bus relay and channel relay of the selected slot are closed.
After the channel relay is closed and then the settling time that is automatically set and the channel
delay time that is specified by the customer elapse, channel switching operation is complete and
the CLOSE output signal of EXT. I/O is turned on (pulse output at the set pulse width).
