terminal strip is composed of Sixteen (16) terminals designated for wiring of input and output signals.   The middle 

and bottom terminal is composed of Eighteen (18) terminals, designated for common and voltage terminals.   -V 

Common is located at Terminals B-16 and B-33;   +V (Voltage In) Terminals is located at C-34 and C-5 terminals.   

For daisy-chaining to nearby Flex I/O module and terminal base, the daisy-chaining terminal is located at C-34 (+) 

and B-16 (-) for supply in and C-51 (+) and B-33 (-) for supply out.   The 1794-TB3K has screw clamp terminals.   

To install the terminal base, position the terminal base at a slightly angled orientation.   Hook the terminal base over 

the top of the DIN rail to attach the back of the terminal base to the DIN rail.   The Terminal base hook must slide 

under the edge of the adapter module and the FlexBus connecter is engaged.   Slide the terminal base and push tight
