About 1734-TB3

The 1734-TB3 is a major component of the POINT I/O product family. This hardware is a Terminal base assembly where POINT I/O modules are installed, signal wires are terminated, and backplane connection is established. The Terminal base assembly also provides the DIN Rail attachment. The 1734-TB3 is a packaged product. It is composed mainly of mounting base and Removable Terminal Block (RTB). It also includes sub-components such as the module hardware locking mechanism and the RTB removal handle. The module hardware locking mechanism is a rotating part of the hardware with numbers embedded onto it. This numbers represent the Keyswitch position rotated via a flat head screwdriver. The keyswitch must coincide the keyswitch position requirement of the POINT I/O module to be able to successfully mount the module. The RTB removal handle provides a convenient way to install and uninstall the RTB without much effort. The 1734-TB3Õs main components are the mounting base and removal terminal block. The mounting base is where the POINT I/O cartridge or module is installed. Additionally, the mounting base provides connection to the POINTBus backplane via the interlocking side pins including connectivity to adjacent modules. The removable terminal block is an Twelve (12) terminal, cage clamp terminal that can be attached and detached to the mounting base when needed without removal of installed signal wires. The recommended wire type for termination to this RTB is a solid or stranded copper wire, with size ranging from 0.25-2.5 mm_ or 22-14 AWG. Wire insulation rating should be 75 ¡C (167 ¡F), or greater and insulation thichness not greater than 1.2 mm or 3/64 in. For a Twelve (12) terminal RTB, the required wire stripping lengths are 14±1 mm (0.55±0.03 in) for 1 wire and 16±1 mm (0.63±0.03 in) for 2 wire. The modularity feature or the RTB helps in faster installation, replacement of the mounting base and maintenance of the system which in turn contributes to faster installation, commissioning and troubleshooting of the system. The 1734-TB3Õs electrical requirements includes a maximum field power bus supply voltage of 300V, maximum field power supply bus current 10A. It is tested and exhibits an isolation voltage of 250V, Basic Insulation Type, field-side to system Type that is tested to withstand 1000V AC for 60 s. The 1734-RTB3Õs physical dimensions are 65mm for Height, 12mm for Width and 160mm for depth or 2.56 inches for Height, 0.47 inch for Width and 6.25inches for Depth. The 1734-RTB3Õs operating temperature requirement is -20É55 ¡C or -4É131 ¡F with surrounding air temperature of 55 ¡C (131 ¡F). To maximize the lifespan of this hardware and other POINT I/O devices, it is important to operate the products within the specified temperature range. To control the temperature of the environment, appropriate cooling and heating device may be installed with respect to the total thermal dissipation of the moduleÕs and electrical devices installed within the enclosure. The 1734-RTB3 has an open type enclosure which means that enclosure selection is based on the actual installation location and area classification.
