About 1734-TOP3

The 1734-TOP3 is an Allen-Bradley manufactured product. It belongs to the POINT I/O product family which is intended to house the POINT I/O module and provide POINT I/O bus interface. The main components of the 1734-TOP3 single terminal base includes the DIN rail locking screw (orange), Handle, Wiring block, Interlocking side pieces and Mechanical keying (orange). It has Twelve (12) terminals that is designed for screw type connection. The 1734-TOP3 is an open-type equipment, intended for indoor use only. It requires installation within an enclosure, appropriately selected, sized and designed in consideration with the specific environmental conditions in the installation area. Proper selection of enclosure contributes to maximizing the hardwareÕs operational lifespan as well as prevent unwanted system operation which in-turn may prevent accidents or injuries. Ideally, the selected enclosure must have a flame-retardant property to prevent or limit the spread of heat and fire, in reference to flame spread rating of 5VA. The enclosure should be easily accessible with the use of a tool. Install suitable climate control devices such as heater or cooler, depending on the local environmental disturbances. Selection of these devices should refer to the moduleÕs temperature operating temperature requirement of -20É55 ¡C (-4É131 ¡F) and maximum surrounding air of max. 55 ¡C (131 ¡F). Point I/O moduleÕs Thermal dissipation as well as dissipation of other devices must be considered when designing climate control system. The 1734-TOP3Õs measures 49mm for Height; 12mm for Width and 144mm for Depth. It weighs approximately 63.8 g or 2.25 oz. The rated maximum supply voltage is 300V and maximum supply power of 8A. It has an isolation voltage rating of 240V (continuous), Reinforced Insulation Type, or the lesser of the installed module. Appropriate signal wire for establishing connection to filed devices can be solid or stranded copper wire with wire size range of 0.25-2.5 mm_ or 22-14 AWG. Recommended maximum thermal insulation rating is 75 ¡C or 167 ¡F or greater and maximum insulation thickness of 1.2 mm or 3/64 in. As the terminal is a screw type terminal, required terminal base screw torque is 0.6 Nm (7 lb-in) and terminal block torque of 0.4 Nm (3.5 lb-in). Screw clamp terminal may tend to loosen tightness when exposed to constant vibration and shock. Ensure that the module is operated in an installation with vibration not exceeding 5 g @ 10É500 Hz per IEC60068-2-6 standard and operating shock of 30 g per EC 60068-2-27 standard. Additionally, vibration and shock panel accessories may be installed to limit the effects of vibration. Use terminal lugs or ferrules to create a more reliable connection. Electrical specification of the 1734-TOP Terminal base includes supply voltage of 300V max terminal voltage and supply power of 8 A max terminal current. Field power bus supply voltage is 28.8V DC, 120/240V AC. The terminal base also connects the POINT I/O system to the system grounding as the productÕs grounding connection is established via the DIN rail. To ensure continuous grounding connection, use a zinc plated chromate-passivated steel DIN rail to assure proper grounding.
