In the face of the complex environment of high temperature, much dust and strong electromagnetic interference in the metallurgical hot rolling production line, a stable and reliable control terminal is the key to ensuring production continuity and operational efficiency. The T-KEY series of industrial membrane keyboards launched by Tianjin Changdatong Technology Co., Ltd. have been officially supplied to the hot rolling production line of a large metallurgical enterprise with their highly integrated and industrial-grade design. They will provide reliable interactive support for the upgrade of the control system of this production line.

Flexible adaptation to multiple scenarios

As two typical configurations in the T-KEY series, both the T-KEY 7800-64C and the T-KEY 7800-128C adopt a highly integrated design, effectively integrating the functions of multiple keys and indicator lights, simplifying the layout of the operation console and on-site wiring.

T-Key7800-64C: Equipped with 64 keys, it is suitable for medium-complexity workstations such as rolling mill control and cooling systems, and supports centralized operation and status feedback.

T-Key7800-128C: Equipped with 128 keys, it is suitable for high-density control scenarios such as the main control console and dispatch center, and supports multi-device collaboration and systematic command interaction.

The three-color indication is clear and intuitive

Both keyboards are equipped with RGB three-color indicator lights, which can display multiple colors through the combination of red, green and blue primary colors. Users can customize the light color according to the on-site process requirements, meeting the visual indication needs of different equipment statuses, alarm levels and process stages, and improving the identification efficiency and accuracy of on-site operations.

Reliable operation in harsh environments

All our products feature an IP54 protection rating and support a wide operating temperature range of -20℃ to 60℃, making them suitable for the common dust, damp heat and vibration environments in hot rolling sites. It adopts a fanless heat dissipation design and long-lasting key components to ensure stable performance under continuous operating conditions.

Seamless integration of industrial protocols

Supports the PROFINET industrial Ethernet protocol, featuring network configuration, topology recognition and fault diagnosis functions, and can be quickly integrated into existing Siemens PLC systems. The dual-port communication design further enhances connection reliability, meeting the high requirements of the hot rolling production line for real-time control and system continuity.

Professional services continuously empower

The T-Key7800-64C and T-Key7800-128C have now been successfully supplied, further expanding the application achievements of Changdatong Technology in the field of metallurgical hot rolling. Changdatong Technology has always been dedicated to the research and development and promotion of high-performance and highly adaptable industrial control products, committed to providing metallurgical enterprises with more intelligent and reliable control operation solutions, and helping the industry achieve control system upgrades and continuous improvement of production efficiency.
