Allen Bradley 1746-N2 is a slot filler that includes an unused I/O slot in the case; It prevents defects in the backplane by helping to prevent debris from falling into the slot. This product also protects unused slots in the case from dust. Following the testing of the application safety requirements EN 61131-2 Programmable controllers Part 2 - Equipment requirements and tests, ensure that the 1746-N2 complies with the Low Voltage Directive Commission Directive 73/23/EEC. Allen Bradley 1746-N2 applies only to Class I, Zone 2, Groups A, B, C, D, and non-hazardous locations. Before installing or removing the module, take care to disconnect from the SLC 500 system and from other sources to the module (in other words, do not "hot swap" any module) and disconnect all devices connected to the module. Failure to take precautions may result in damage to the equipment.
Allen Bradley 1746-N2 measures 12.7 x 7.62 x 20.32 cm (5 x 3 x 8 in). The weight of the slot filler is about 0.045 kg. Its operating temperature ranges from -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit), while its non-operating temperature ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The relative humidity of the tank filling fluctuates between 5% and 95%, with no condensation. At 10 to 500 Hz, its working vibration is 2 g and its working and non-working shocks are 30 g.
