Applications

The DirectLogic 205 (DL205) is a compact, modular PLC platform widely used in small to mid-size machine control, material handling, conveyor systems, packaging equipment, and general factory automation. The D2-03B base is the smallest chassis in the DL205 family, accommodating one CPU module and up to two I/O modules. Compatible DL205 CPU modules include the D2-230, D2-240, D2-250-1, and D2-260, and the system supports a broad range of discrete and analog I/O modules. The DL205 platform was introduced in the 1990s and remains in active use across many industrial facilities due to its reliability, the wide availability of spare parts, and continued software support through PLC Direct's Do-more and DirectSOFT programming environments. It communicates via DirectNET and Modbus RTU protocols and is a common choice for legacy system maintenance and ongoing automation projects.
