maximum external pull-up level is 12 V, maximum port current is 300 mA, and the
default output signal is high-level (external pull-up voltage). The default output signal
switches to low- level when an alarm is triggered (As long as the operating current is
below 300 mA, the output low-level voltage is lower than 0.8 V).
●
Mode B: Switch application. Alarm output is used to drive the external circuit. The
maximum voltage is 12 V and the maximum current is 300 mA. If the voltage is higher
than 12 V, please use an additional electric relay.

Log in to the webpage, and then configure the alarm input and alarm output in alarm
settings.
●
The alarm input on the webpage corresponds to the alarm input end of the I/O port.
There will be high level and low level alarm signals generated by the alarm input device
when an alarm occurs. Set the input mode to "NO" (default) if the alarm input signal is
logic "0", and set to "NC" if the alarm input signal is logic "1".
●
The alarm output on the webpage corresponds to the alarm output end of the device,
which is also the alarm output end of the I/O port.
