The ULTRA (U) series has two Ethernet ports built in that can act as a switch.
The maximum number of connected inputs / outputs is 352 I / O points using up to 10 expansion modules. As the only series of controllers I support EtherCAT type communication. These units have a built-in real-time clock (RTC), an SD memory card slot with the ability to log data. Models are available with an integrated analog-to-digital and digital-to-analog converter and positioning functions in many axes, many interpolation algorithms. They have a large program memory of 30,000. steps.
