The ABB TB810 is a Modulebus network terminator designed for distributed automation systems. Its primary function is to terminate Modulebus communication lines to prevent signal reflections, ensuring reliable communication across I/O modules and control devices. Proper termination is critical in industrial automation networks, particularly where multiple devices are connected over long bus lines.
The TB810 is engineered for industrial-grade performance with a compact form factor suitable for DIN rail or Modulebus rack installation. It is compatible with ABB S800 I/O systems and other Modulebus-based distributed control networks. This device is passive, requiring no external configuration or power supply, yet it ensures stable data transmission across complex automation setups.
