Wiring the Digital Input (DI) 

 

The  Digital  Input  (D.I.)  contacts  are  in  the  bottom  side  of  the  device  as  shown  in 
below figure. 
It  accepts  one  external  DC  type  signal  input  and  can  be  configured  to  send  alert 
message  through  Ethernet  when  the  signal  is  changed.  The  signal  may  trigger  and 
generated  by  external  power  switch,  like  as  door  open  trigger  switch  for  control 
cabinet.   

 

 
 
 

 

 

 

Note: the DI accepts DC type signal and supports isolated input circuit with Digital High
Level input DC 11V~30V and Digital Low Level input DC 0V~10V. Do not apply voltage that
higher than the specification; it may cause internal circuit damage or a wrong action of DI.
