Allen-Bradley 1794-TB3

Each FLEX I/O™ module requires a terminal base unit that 

snaps onto the DIN rail to the right of the I/O adapter. The 

terminal bases provide terminal connection points for I/O 

wiring and plug together to form the backplane. They are 

available with cage, screw or spring - clamp terminations.

Each FLEX I/O module has optional accessories available 

depending on the I/O module, field system set-up and 

requirements.
