Besides the expansion modules, XC series PLC can also expand by the BD cards. The BD cards 
are small PCB cards which can insert into PLC from the BD port (on CPU unit), so this kind of 
expansion doesn't take extra space.     
l  Analogue and temperature type: XC-2AD2PT-BD   
l  Communication: XC-COM-BD 
 
※1: User should install and configure before using the BD cards. For details, please refer to:《XC series BD cards 
user manual》.
