3.5.16 Status Output (option code AL)
This feature is used for a transistor output (open
collector) of an on/off signal according to the status of
high and low alarm limits, which are user-configurable
values as shown in 3.5.15 Process Alarm. The status
output can be assigned as any combination of the high
or low limits of the input pressure, input static pres-
sure, or capsule temperature.
NOTE
No status output signal has been defined for a
CPU failure or hardware error. Use a 4-20 mA
signal to indicate a transmitter’s failure.
