NOTES: 
▪ AC output ratings are only applicable to Model 
FDCIO422  interface  modules  that  have 
Engineering State (ES) version ’10’ or higher. 
▪ The  part  number  (S54322-F4-A1)  for  Model 
FDCIO422  is  found  on  the  back  of  each 
interface module, and the ES version is placed 
just  the  right  of  the  part  number.  (See 
illustration). 
▪ Refer  to  Installation  Operation  Manual,   
IOM:  A6V10324662,  for  further  details.

NOTES: 
▪ Verify control panel  supports Class-X mode for 
FDCIO422 module of ES30 or higher. 
•  Class  X  mode  must  be  used  with  FDCIO422, 
modules  that  have  Engineering  State  (ES) 
version ’30’ or higher.
