Example I/O Wiring for X and XA CPU Units
Input Wiring
The input circuits for X and XA CPU Units have 24 points/common. Use power
lines with sufficient current capacity for the COM terminals.
Upper Terminal Block
AC-power-supply models have a 24-VDC output terminals on the lower termi-
nal block. They can be used as a DC power supply for the input circuit.
To use high-speed counters, make the following setting in the PLC Setup.
Enable using the high-speed counters with Built-in Input - High Speed
Counter 0 to 3 - Use high speed counter 0 to 3. For details on high-speed
counter inputs, refer to 2-2-3 I/O Specifications for XA and X CPU Units.
