PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1747-L533/E (Series E). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1747-L533 SLC 500 Controller provides thirty-two thousand words of total user memory. The memory architecture allocates twenty-eight thousand words for program instructions and data tables. The remaining four thousand words serve dedicated data storage requirements. The controller uses battery-backed random-access memory for volatile program data retention.
This modular unit installs into an open-style SLC 500 chassis backplane. It addresses up to three local chassis and thirty module slots total. Channel zero provides RS-232 communication supporting DF1 or ASCII protocols. Channel one provides DH-485 network connectivity for peripheral devices. RSLogix 500 software manages system programming and diagnostics.
