Information About 1734-TOP

The 1734-TOP POINT I/O Terminal Base by Allen Bradley is a one-piece base, meaning that its purpose is as a mounting base with an integrated 8-terminal screw-clamp block. It has a wide range of applications in industrial automation because it provides wiring of digital input/output/relay modules, analog input/output modules, and specialty modules. This POINT I/O terminal base can be mounted directly on the DIN-rail, either horizontally or vertically, and will connect distribution of field power-bus as well as backplane communication. The mechanical keying of the terminal base prevents incorrect module placement. While the POINT I/O system implements a No-Tools design, providing a smooth assembly process to set up the I/O module with the terminal base, without using any tools.

A handle, a DIN-rail Locking Screw and Mechanical Keying (both Orange), and a wiring block are the main components of the 1734-TOP terminal base, all kept within dimensions of 49 x 12 x 144 millimeters (1.93 x 0.47 x 5.67 inches) and a weight 63.8 grams (2.25 ounces).

This terminal has a wire size of 0.25 or 2.5 millimeters, (that is 22 to 14 AWG), a screw torque of 0.6 Nm (7 pound- inch), while its supply voltage has a maximum of 300 Volts, its terminal current a maximum of 8A, and a field power bus supply voltage ranging from 28.8 Volts DC to 120 or 240 Volts AC.

To begin installation of the 1734-TOP module, vertically position the base above any existing units (adapter, existing modules or power supply), and slide the base down to allow it to interlock with the terminal’s side pieces and engage the units directly on either side. Finally, press the module firmly down to seat it onto the DIN rail until it snaps into place. Its locking screw should be kept horizontal and in a “locked” position prior to the insertion of an I/O module.

The POINT I/O is grounded through the DIN rail to chassis ground. Use a zinc plated yellow-chromate steel DIN rail to assure proper grounding. The single terminals pins are designated with the numbers 0 to 7 and the connections are determined by the I/O module being used. Any single terminal pin should not have more than 2 conductors wired to it.

The POINT I/O modules that can be used with the Allen-Bradley 1734-TOP terminal base are as follows (with the mechanical keying number in parenthesis): (1) 1734-IB2,1734-IB4, 1734-IB8, 1734-IV2, 1734-IV4, 1734-IV8, 1734-OB2, 1734-OB4, 1734-OB8, 1734-OB2E, 1734-OB4E, 1734-OB8E, 1734-OB2EP, 1734-OV2E, 1734-OV4E, 1734-OV8E; (3) 1734-IE2C, 1734-IE2V; (4) 1734-OE2C, 1734-OE2V; (5) 1734-CTM, 1734-VTM; (7) 1734-OW2, 1734-OW4, 1734-OX2; (8) 1734-IA2, 1734-IA4, 1734-IM2, 1734-IM4, 1734-OA2, 1734-OA4.
