Visualize the actual worksite status!
Simple and Intelligent I/O Slave Units.
In addition to the Digital I/O Slave Unit's basic digital ON/OFF sig-
nals, collect useful information from the Slave Unit to improve
equipment operating rates and maintainability.
• Communications connector and removable I/O terminal block enable faster
startup times and improved maintainability.
• One Expansion Unit can be added to each Digital I/O Slave Unit to increase
system configuration flexibility.
• Collect various preventive maintenance data required to improve productivity,
such as information on equipment deterioration due to aging and equipment
operating time data.
• Simplify startup with the communications power supply monitoring function.
Ordering Information
Note: These Units are also available with a DCN-TB4 Terminal Conversion Adapter included in the package. Add "(-B)" to the end of the model number to receive the
Adapter as well.
●Expansion Units
One Expansion Unit can be combined with one Digital I/O Slave Unit (CRT1-ID16(-1), CRT1-OD16(-1), CRT1-ROS16, or CRT1-ROF16).
The following Expansion Units are available. They can be combined in various ways for flexible I/O capacity expansion.
