FX1N Series Programmable Controllers Legacy Information

Background: Introduced in 2000 the FX1N added additional functionality over the FX0N and provided additional means of expandability with the possibility of expanding to the right and the left. The FX1N could use the FX2N Series adapter boards and special function blocks, which in combination with the available expansion boards provided an unprecedented variety of expansion options.

Lifecycle: Introduced (2000) - Discontinued (December 2015)

Service Life: Repair Period Ends 2022

Migration Info

The FX5U should be used in place of the FX1N PLC. The FX5U has the same I/O configurations as the FX1N and the terminal blocks can be removed from the FX1N and placed in the FX5U, so no additional wiring is required. Programs can be imported into the latest GXWorks3 software platform, but some review is necessary to ensure that all functions of the program are migrated successfully. Please contact your local Mitsubishi representative if additional assistance is required.

• Suggested part numbers are not always drop-in replacements
