Typical Scheduled Output Example
A ground water site using an iRIS 320 is required to log a sample every hour that is obtained from a pressure
transducer whose power supply is controlled from the digital output, DO1 via a transistor switch. The
transducer needs to be powered up for one minute prior to the measurement being taken and logged. The
settings required for DO1 to achieve this are shown below.

4 Duration [65 sec]
5 Frequency [60 min]

The output will be activated at the beginning of the 59
th
minute of each hour in the day, starting at 00:59. It
will remain on for 65 seconds, ensuring that the sensor is still powered up at the point when the reading is
captured on the hour. The final output activation for the day will occur at 23:59 in preparation for the
midnight measurement.
