.
*1. Y002 is not available in 14-point and 24-point type
FX3G PLC.
*2. High-speed input/output special adapters can be connected only to the
FX3U PLC.
*3. To use Y002 and Y003 with a high-speed output special adapter, connect a second high-speed output
special adapter.
Point:
To use an FX
3U Series main unit of relay output type, be sure to connect a high-speed output special adapter.
Differential line drive type outputs will be used for the outputs of the high-speed output special adapter.
