It runs on 100-240 VAC and holds 32K steps of program in EEPROM. Cycle time is 210 ns for basic instructions, 500 ns for MOV. Includes USB and RS-422 ports. Expandable to 128 local or 256 total I/O points. The FX3S-20MT/ES is a smaller, fixed-I/O sibling in the same family. It offers 12 inputs, 8 transistor sink outputs, and no expansion. The FX3G-40MT/ESS doubles the I/O count, uses source output logic, and supports expansion modules up to 256 total I/O. If a panel needs more than 30 I/O points or future growth, the FX3G is the correct fit. The FX3S is for standalone machine sections with a fixed I/O count. The FX3G-40MT/ESS is listed at the mature lifecycle stage.","metaTitle":"Mitsubishi FX3G-40MT/ESS PLC, 40 I/O, transistor source","metaDescription":"Sourcing the FX3G-40MT/ESS? 24 inputs, 16 transistor source outputs, 32K steps EEPROM, expandable to 256 I/O.
