Alarm Output – Level Application
Use this alarm output configuration if the output triggers an external device by increasing the voltage.
The alarm must increase the external pull-up resistance to trigger (high level) the device. The
maximum external pull-up level is 5 V and the maximum port current is 5 mA. Once the output
increases the pull-up resistance, the alarm decreases the output voltage to the normal state (low level)
at less than 0.8 V.
Alarm Output – Switch Application
The alarm output drives the external circuit, with a maximum current of 30 mA and a maximum
voltage of 5 V. It is recommended to add a relay if the circuit exceeds the maximum values.
