1. Product NameUnifi NV Series TC – net I/O Loop Hub Module
2. 
3. Product DescriptionThe TOSHIBA UTLH21 is a key TC – net I/O loop hub module belonging to Toshiba’s Unifi NV series of industrial controllers. It is specially developed for high – demand industrial automation scenarios and serves as a central communication hub in industrial control systems. The module adopts the industry’s pioneering 100 Mbps fault – tolerant ring network technology named “TC – net I/O”, which enables it to stably connect remote and field – mounted I/O devices to the main controller.
   It excels in high – speed data transmission and reliable network management, being capable of efficiently managing data transfer and network traffic among multiple I/O modules. With an industrial – grade rugged design, it can resist electromagnetic interference and adapt to harsh working conditions in industrial sites. In addition, it implements advanced hardware designs such as redundant modules and ECC memory error correction technology, which greatly enhances the stability and fault tolerance of the entire control system during long – term continuous operation.
   This module is widely applied in industrial fields like manufacturing production lines, mechanical equipment control, and process control. It plays an irreplaceable role in tasks such as sequencing control, motor speed regulation, and continuous industrial process control, and can also reduce wiring complexity between electrical rooms and machinery when matching field – installed I/O modules.
