Single-channel Mode
When the output channel is in the On state and without any faults, the safety
outputs turned on. The status is normal. If a fault is detected on the output
channel, the safety output data and individual safety output status turn off.
For information about how using single-channel mode with a 5094-OB16S or
5094-OB16SXT module affects the safety application suitability level, see
Table 16 on page 77
