The Allen-Bradley 1734-TBQ10 is a Point I/O System Box of 10 Terminal Base Assemblies. This product consists of 10 terminal base assemblies corresponding to the part 1734-TB. This product’s great feature is pluggable terminations, also called Removable Terminal Blocks (RTBs). The 1734-TBQ10 has 10 pieces of 8-terminal cage-clamp terminal base assemblies. It supports a POINT I/O system highly modular design and reliable structural integrity. Various types of field devices are easily wired through these wiring base modules to I/O modules. This unit's design and POINT I/O concept together provides an option for the hot swapping of I/O modules. RTBs are a detachable part of this assembly, enabling Removable Terminations Under Power (RTUP). The 1734-TBQ10 base housing provides uninterrupted backplane and Fieldbus power.

The 1734-TBQ10 terminal base box has dimensions of 65 x 120 x 160 millimeters (2.56 x 4.72 x 6.25 inches) and is adapted to fit the space-saving requirements. Its overall technical specifications include a 0.34 to 2.1 millimeters (22 to 14 AWG) acceptable wire size range, a weight of 975 grams (34.4 ounces), a supply voltage of 300 Volts, and a 10A maximum current. Its field power bus supply voltage hangs between 120 to 240 Volts of AC energy, or, alternatively, 28.8 Volts of DC energy.

The composition of the 1734-TBQ10 itself as well as its integration process to the POINT I/O system implements a “No Tools” type of principle. The subparts of the wiring base module and its connection to the POINT I/O system are conducted over simple maneuvers that can be done easily by hand. Place the assembly above previously established terminals and glide it downwards until it fits onto a DIN-rail. Ensure that the orange locking screw is in its locked position, forming a horizontal line. If there is a need to replace the base of the module, do not need to remove wiring. Instead, just pull the handle on the RTB and remove it from the base. Replacement RTBs can be ordered separately using the code 1734-RTB which will correspond to the correct part.

The Allen-Bradley 1734-TBQ10 assembly can match up with almost any I/O module (keying number). Listed here are the modules that will function with the 1734-TBQ10: 1734-IB2/1734-IB8/1734-IV/1734-IV/1734-OV2/1734-IV8/1734-OB2/1734-OB4/1734-OB2EP/1734-OB8/1734-OB4E/1734-IB4/1734-OB2E/1734-OB8E/1734-OV4E/1734-OV8E (Ref.1); 1734-IE2V/1734-IE2C (Ref.3); 1734-OE2V/1734-OE2C (Ref.4); 1734-CTM/1734-VTM (Ref.5); 1734-OW4/1734-OW2/1734-OX2 (Ref.7); 1734-OA2/1734-IM2/1734-IA2/1734-OA4/1734-IA4/1734-IM4 (Ref.8).

It is highly important to correctly set the Mechanical keying number on the mounting base. This is used to prevent installation of an incorrect I/O module in the wiring terminal.
