Expansion Units
XWT-ID08(-1)/OD08(-1)/ID16(-1)/OD16(-1)
Expansion I/O Units make expansion
easy!
One Expansion Unit can be added to each Digital I/O Slave Unit.
This makes a variety of I/O combinations possible, such as 16
inputs + 8 outputs, extending the range of possible system
configurations.
• Flexible expansion with many different combinations.
• Detachable I/O terminal block enables faster startup time and improved
maintainability.
• Collect various preventive maintenance data required to improve productivity, as
information on equipment deterioration due to aging and equipment operating time data.
