The Allen-Bradley 1734-TB3Q10 is a Point I/O System Box of 10 Terminal Base Assemblies. It contains a set of Removable Terminal Blocks (RTB) with 12 separate wiring locations, as well as 10 pieces of a 12-terminal cage-clamp terminal base assembly. Larger projects containing a POINT I/O system require a greater amount of I/O modules, which the 1734-TB3Q10 10 pack terminal base assembly can easily provide. Power distribution and communication have been implemented heavily through the backplane of the 1734-TB3Q10 terminal base assembly, making it the best way to prevent personnel from coming into contact with electricity, and a good method of mechanical protection for the part’s wiring.

The 1734-TB3Q10 is a 10 piece box of 1734-TB3 parts; when they are all connected together, the total compact design is about 65 x 120 x 160 millimeters in dimensions, weighing in at approximately 975 grams (or 34.4 ounces), with a supply voltage of 300 Volts at it maximum and a 10A maximum current. Additionally, its field power bus supply voltage can be either 120 to 240 Volts of AC energy input or 28.8 Volts of DC energy.

One of the most useful features of the module is its mechanical keying. Each I/O module that will be connected to a wiring base has a distinct key number, which should be set on a terminal base prior to installation. This is a design feature that prevents the installation of the incorrect I/O Module.

The 1734-TB3Q10 is easily mountable on a DIN-rail (with both a horizontal and a vertical option) without needing any tools. A Removable Terminal Block is part of every 1734-TB3 assembly, coming handy when there is a need for a quick base replacement, as there is no need to manage its wire system. Just remove the entire RTB and replace the base of the module.
