DIGITAL OUTPUT

The LogBox BLE has a PNP-type digital output which, when triggered, places the voltage from the external source to the digital output pin. The
LogBox BLE digital output can be disabled or configured to operate in one of the modes described below:
● Auxiliary Electronic Switch: Used to control the power supply of external instruments during analog channel readings.
Ex.: 4-20 mA transmitters can be powered by the digital output pin, so that they can only be turned on at the time they are read, thus, saving
power from LogBox BLE external power supply, which can be a 12 V battery. In the "Auxiliary Electronic Switch" mode, it is necessary to set
how long before each acquisition the digital output must be triggered.
○ Drive Time: Set, in seconds, how long before each acquisition the digital output must be triggered. It is deactivated as soon as the
acquisition is complete. This time cannot be longer than the lowest acquisition range (Instantaneous, Average = 1/10 of the instantaneous,
Display Interval). If equal to 0, the Auxiliary Electronic Switch will be enabled at the exact moment of an acquisition. If greater than or equal
to the lowest acquisition interval, the Auxiliary Electronic Switch will always be enabled.
● Alarm Status: Used to track the current general alarm status. If any channel is in an alarm situation, the digital output is triggered. If no channel
is set to alarm, the digital output is disabled.
