The indicated outputs are dedicated for control when enabled in the loop setup. If one or both of the outputs are disabled for
a loop, then the corresponding digital outputs become available for alarms.

If you install a Watlow Serial DAC, the D8 series controller uses digital output 18 (terminal 15) for a clock line. You cannot use
output 18 for anything else if a Serial DAC is installed.
