• As a digital output, it can trigger an alarm, siren, door lock or opens a valve

or a switch. Pin 4 is an open collector transistor output normally at 3.3VDC.

When triggered, it is pulled to ground. The initial state of the digital output

when the device is rebooted is configurable in ALEOS.

• As an analog voltage input, it detects inputs of 0–30VDC across this pin to

ground. When used with a converter to transform values into voltages, it

monitors measurements like temperatures, pressures or the volume of liquid

in a container. ALEOS can transform these voltages into meaningful values.

In ALEOS, events reporting tells the device to perform an action when a

specified voltage is detected.
