The CX-DO08 is a next-generation industrial IO controller developed by Come-Star, designed for reliable digital output control and seamless data handling in demanding industrial applications. Featuring an expandable modular design, the unit supports RS485 communication and is fully compatible with the Modbus RTU protocol, ensuring fast deployment and wide system compatibility.
The controller offers 8-channel digital output, with clear LED indicators to help users monitor device and output status in real time. With multiple models available, the CX-DO08 can be easily tailored to diverse project needs and flexibly combined with other IO modules on site.
It also integrates smoothly with Cgate100 and Cgate300 controllers to enable powerful, scalable industrial automation solutions.
