1746-A10 SLC 500 Ten-Slot Chassis

Overview

The Allen-Bradley 1746-A10 is the expansion backbone for SLC 500. Its robust backplane and keyed slotting make it simple to house a CPU, digital and analog I/O, and communication cards such as DH-485, RIO, and serial bridges.

Choose the 1746-A10 when panel space allows and you want future-proof capacity for machine upgrades or spares consolidation.

Engineering & Design

The chassis provides 10 module positions for the CPU, I/O, and communication modules, with clear slot numbering that simplifies wiring and documentation. The proven 1746 backplane is engineered for 24/7 industrial duty, and the keyed slotting prevents incorrect module installation.

Integration is straightforward because the chassis is compatible with standard SLC 500 power supplies and modules, allowing the existing module inventory to be reused when consolidating panels.

Specifications

For SLC 500 expansion, the 1746-A10 SLC 500 chassis is the backbone, and Seven Star LLC supplies the 1746-A10 SLC 500 chassis for your system upgrade.

The Allen-Bradley 1746-A10 is the 10-slot chassis of the SLC 500 system and holds the power supply, the processor and the I/O modules of the controller. The chassis is mounted in the cabinet with the mounting brackets and the modules are inserted in the card guides. The backplane of the chassis distributes the power and the data to the installed modules. The addressing of the I/O is determined by the slot number of the module.

The chassis is ordered with the keying for the module protection and the key bands are set to the module family. The spare chassis allows the extension of the existing SLC 500 station with the additional module slots. The 1746-A10 is compatible with the SLC 5/01, 5/02 and 5/03 processors of the family.

The wiring of the chassis is made with the removable terminal blocks of the modules, and the backplane connectors are protected during the module exchange. The replacement of the chassis is performed with the power off and the modules are transferred to the new rack in the same slot order.

The 1746-A10 chassis is ordered with the backplane expansions and the power supply for the CPU of the station. The chassis is mounted with the four screws on the panel and the ground braid connects the rack to the cabinet ground. The slot keys are set for the module family and the spare chassis supports the station extension. The data table and the I/O addressing are documented for the slot assignment of the program.

The 1746-A10 chassis is the standard rack of the SLC 500 control panels and the processor module is installed in the first slot. The backplane supports the communication modules and the programming port of the CPU. The rack is ordered with the keying band kit for the module protection of the installed system.
