GE / IP FANUC Series 90/30 In Stock
The Allen-Bradley 1746-A10 is a modular chassis used with the SLC 500 system. The 1746-A10 has 10 slots for mounting tabs. Its modular nature helps to configure the system depending on its size. Users can shrink or expand the system. To expand the module slots to 30 slots, use the chassis interconnect cables to interconnect with other chassis. The Input/Output adapter or the processor are placed on the left most slot in the 3-chassis group. The 1746-A10 has 6 mounting compartments. When installing the 1746-A10, make sure to provide for enough grounding. For grounding, use the grounding bus.
The grounding cable should be 14 AWG in size. When connecting to the ground bus, use a 10 AWG copper wire to connect each chassis and use a steel enclosure to prevent EMI interference. To minimize the dependence on the viewing window hinges for the electrical contact between the door and the enclosure, install a dedicated bonding wire. The grounding electrode used with the 1746-A10 should have a minimum of 8 AWG copper wire size.
Inside the 1746-A10, make sure proper spacing is achieved to ensure proper air ventilation inside the chassis. Use short wires to interconnect modules inside the 1746-A10. The 1746-A10 measures approximately 16.9 x 6.8 x 5.8 inches, it weighs 1.45 kgs without modules, and it has a backplane current of 10A at 5.1V DC, and 2.88A at 24V DC. The 1746-A10 is rated to be operated at temperatures between 32 degrees Fahrenheit and 140 degrees Fahrenheit, and it can be stored at a storage temperature between -40 degrees Fahrenheit and 185 degrees Fahrenheit. The 1746-A10 is recommended for use in environments with a non-condensing relative humidity of between 5 and 95%.
