Latched:
A latched mode operates with at least one other channel
set to latched mode. For example, if channel 1 and 2 are set to
latched mode, pushing button 1 on the SFT900-4 will turn relay 1
on the SF900. Pushing button 2 will turn off relay 1 and turn on
relay 2. This mode is often used when a separate on and off
button is desired. If more than 2 channels are selected for latched
mode, only 1 relay can be activated at any given time. Any
activated relay will result in the others being turned off.
