Automation Direct D2-CM Expansion Controller Module is the local expansion controller for the DL205 DirectLogic PLC family. Inserted into the CPU slot of each expansion base (up to four total), the D2-CM uses a rotary switch to set a unique expansion-base number that the DL205 CPU recognizes. It is designed for use with D2-250-1 and D2-260 CPU-based DL205 PLCs to enable expansion bases and local I/O, often in conjunction with D2-EM expansion modules.
