Quick Start Guide
2
Connect the alarm input device to the alarm input end of the I/O port.
The device collects different statuses of the alarm input port while the input signal is idling
and being grounded.
Device collects logic "1" when the input signal is connected to +3 V to +5 V or idling.
Device collects logic "0" when the input signal is grounded.
Alarm input
Connect the alarm output device to the alarm output end of the I/O port. The alarm output is
an open-drain output, which works in the following modes.
Mode A: level application. The alarm outputs high and low level signals, and the alarm
outlet is OD, which requires external pull-up resistance (10 K Ohm typical) to work. The
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, use an additional electric relay.
Alarm output
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 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.
