| Built-in RS-485 | No |
| RS-485 Expansion | Serial communication can be added using compatible FX5 expansion board/adapter |
| Built-in Analog I/O | No |
| Analog Expansion | Compatible FX5 analog expansion adapters/boards can be used for analog applications. |
| SD Card Slot | Not built in; optional SD memory-card functionality can be added using a separately sold module. |
| High-Speed Counters | Up to 8 channels |
| High-Speed Counter Performance | 4 channels × 100 kHz + 4 channels × 10 kHz. |
| Built-in Positioning | Up to 4 axes on transistor-output CPU models |
| Maximum Positioning Frequency | Up to 100 kpps per supported axis. |
| Positioning Output Requirement | Built-in positioning is available on transistor-output CPU versions, not relay-output versions |
| Expansion Board | Supports 1 compatible expansion board |
| Expansion Adapters | Supports compatible functional expansion adapters; Mitsubishi documentation specifies up to 6 adapters subject to device/system restrictions. |
| Standard Extension I/O Modules | Not supported on FX5S; this is a key difference from FX5UJ/FX5U |
| AC Power Models | /ES and /ESS variants |
