Overview
The ABB TU849 Termination Unit is engineered to provide robust connectivity and redundancy in distributed control systems. It supports dual power supply connections, redundant modem configurations, and secure electrical ModuleBus integration. Moreover, the TU849 is DIN‑rail mounted with a mechanical latch for easy installation and maintenance. In addition, its rotary switch allows cluster address settings from 1 to 7, enabling flexible system design. Therefore, it is widely adopted in ABB’s 800xA and AC 800M automation platforms where high availability and fault tolerance are essential.
