CT1721C (CUBLOC based touch screen controller)

CT1721C is an all-in-one touch controller that integrates a CUBLOC controller, mono graphic LCD, and touch panel into a single compact unit. Using BASIC programming, users can easily display graphics and text on the LCD and design intuitive user interfaces such as buttons, menus, and data input screens without complex PC-based HMI software.

External devices and field equipment can be connected through the rear I/O ports, allowing reliable and deterministic I/O control using IEC-based Ladder Logic. By combining HMI functionality and PLC control in one device, CT1721C significantly simplifies system architecture while reducing development time, wiring complexity, and long-term maintenance costs.

CT1721C is a long-standing steady-seller that has been widely deployed in industrial environments for many years. Its stability, reliability, and practical effectiveness have been thoroughly proven through extensive real-world applications, making it a dependable touch-based controller for systems requiring long-term continuous operation.
