Product Overview
The Allen-Bradley 1794-TB3G is a terminal base unit in the Flex I/O 1794 platform. It provides connection points for up to 36 I/O terminals plus two common and two +Voltage terminals via screw-clamp wiring, and forms the backplane for Flex I/O modules including analog, RTD/thermocouple, and counter modules. Typically installed on DIN rail, it supports module stacking for distributed control or data acquisition systems in industrial automation environments. 1794-TB3G is used to mechanically and electrically interface Flex I/O modules to the system backplane, enabling signal wiring and power distribution.
