Allen-Bradley 1794-TB32S Spring-clamp Terminal Base Unit

Allen-Bradley 1794-TB32S Spring-clamp Terminal Base Unit

Description

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. 

Mount the Terminal Base Unit on a DIN Rail：

1. Remove the cover plug (if used) in the male connector of the unit to which you are connecting this terminal base unit.

2. Check to make sure that the 16 pins in the male connector on the adjacent device are straight and in line so that the mating female connector on this terminal base unit will mate correctly.

3. Make sure that the female connector (B) is fully retracted.

4. Position the terminal base unit on the 35 x 7.5 mm DIN rail (A) (Allen-Bradley® catalog number 199-DR1) at a slight angel and hook it over the top of the DIN rail.

5. Make sure the hook (C) on the terminal base slides under the edge of the adapter and the Flexbus connector is fully retracted. Slide the terminal base over, tight against the adapter.

6. Rotate the terminal base onto the DIN rail with the top of the rail hooked under the lip on the rear of the terminal base. Make sure that the female Flexbus connector does not strike any of the pins in the mating connector.

7. Press down on the terminal base to lock it on the DIN rail. If the terminal base does not lock into place, use a screwdriver or similar device to open the locking tab, press down on the base, and release the locking lever to lock the base in place.
