Information About 1746-A7

The Allen-Bradley 1746-A7 houses the modular processor, communication adapter module, and input and output modules. This chassis is built with 7 slots that is part of the SLC 500 Modular Chassis that provide flexibility in the configuration of systems. In a modular system, each chassis will require its own power supply. The SLC 500 1746-A7 Modular Chassis can be used as a standalone unit in one system or can work with another one or two local chassis. The chassis interconnection cable can be used to build multiple chassis configurations and extend signal lines. This can create a total of 30 I/O slots at maximum. Interconnect chassis vertically with the 1746-C9 cable or 1746-C16 cable that comes in different lengths. Both cables have a rigid, unbending shrink wrap for strain relief when linking modules with one below another. For a horizontal layout, use the 1746-C7 cable. Do not use any other cables for the setup. Longer cables may affect data communication integrity leading to unsafe operation.

Running a ground connection from the 1746-A7 Chassis to the ground bus reduces electrical resistance. When grounding, do not lay one lug directly on top of another. Compression can cause these connections to become loose. The 1746-A7 has a maximum backplane current of 5.1 Volts DC at 10A or  24 Volts DC at 2.88A. For optimal performance, operate in temperatures between 0 degrees Celsius to 60 degrees Celsius (32 to 140 degrees Fahrenheit), and relative humidity of 5% to 95% (without condensation).

The 1746-A7 is an SLC 500 chassis that provides mounting to SLC 500 modules such as SLC processors, SLC IO modules, SLC Communication adapters and specialty modules.

The 1746-A7 features Seven (7) slots with which may be expanded up to 21 modules by connecting an additional of Two (2) more chassis from the main chassis where the controller resides. This is done with the use of interconnection cables with part number 1746-C9, 1746-C7 and other interconnect cables with varying lengths. Each chassis requires an individual power supply but only one SLC 500 processor is needed. This processor shall be stationed or installed to the main chassis. The expansion chassis are treated as remote IO racks.

SLC 500 comes with other variants of chassis including 1746-A13, 1746-A10 and 1746-A4. All of these chassis, including the 1746-A7 has an embedded electronic circuitry which is connected to the Power Supply slot. This circuitry is used as the backplane where power is distributed to the inserted modules. It also serves as the information exchanged between the processor and modules therefore, an SLC 500 Modular Style controller cannot be operated without a chassis.

In other terminologies, chassis may also be referred to as Rack or Backplane. In typical applications, this chassis is installed horizontally. If more than one chassis is needed by the system, side by side installation is also permitted provided that there is accurate panel space and the recommended separation of 7.7 cm to 10.2 cm or 3.0 to 4.0 inches is maintained.
