alarm output, the relay occupies 2 pins, pin definition are
shown as above. 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 and Model IV
The Model III and IV device of this series provides
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】
The device provides 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:
