terminal blocks and support 1 relay alarm output, the relay
occupies 2 pins, pin definition is shown in the above figure. R1
and R2 are a group of normally open contacts of the device
alarm relay, which is open in normal no-alarm state and
closed when any alarm information appears. For example,
they are closed when powered off, and send out alarm. The
relay supports the output of DC power supply alarm
information or network abnormality alarm. It can be connected
to alarm light or alarm buzzer or other switching value
collecting devices, which can timely inform operators when
the alarm occurs.
Model III, Model IV, and Model V
The Model III, Model IV, and Model V provide
7-pin M23 interface, pin 5 and 7 are relay pins.
The relay is a group of normally open contacts,
which is open in normal no-alarm state and closed
when any alarm information occurs. For example, they are
closed when powered off, and send out alarm. The device
supports 1 relay alarm information output that can output
network abnormality alarm. It can be connected to alarm light
or alarm buzzer or other switching value collecting devices,
which can timely inform operators when the alarm occurs.
【Console Port Connection】
Provide 1 program debugging port based on
RS232 serial port which can conduct device CLI
command management after connecting to PC.
The interface adopts RJ45 port, the pin definition as follows:
