PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1747-M11 is an SLC 500 Flash Memory Module - 32K designed for hardware program backup. It provides 32 KB of non-volatile Flash EEPROM storage for compatible modular controllers. Supported processors include the SLC 5/03, SLC 5/04, and SLC 5/05 series. Specific controller part numbers include 1747-L532, 1747-L541, 1747-L542, and 1747-L543 units. The module retains user programs without requiring active battery power.
Hardware compatibility varies across module series revisions. The 1747-M11 Series A module installs into SLC 5/03 Series A or Series B processors. The 1747-M11 Series B module operates with SLC 5/03 OS302, SLC 5/04 OS401, and SLC 5/05 processors. It does not support 1746-BAS or 1746-BAST modules. Burning firmware or code with an external PROM programmer requires a 1747-M15 adapter socket.
