Memory Architecture: EEPROM-based latching for auxiliary relays (M500–M1023) and data registers (D200–D511) ensures data retention without batteries.
High-Speed Processing: Supports up to 100 kHz single-phase and 50 kHz two-phase counter inputs for precise motion and encoder feedback.
Scalability: Compatible with FX3U/FX3UC expansion modules for up to 256 I/O points (local) and remote I/O via CC-Link.
Communication: Built-in RS-422/485 port for programming and networking, plus optional Ethernet, Profibus, or CANopen adapters.
Timing Precision: 1 ms timers (T246–T249, T256–T511) enable microsecond-level control for fast-acting outputs.
Data Logging: 32,768 extension registers (R0–R32767) support large-scale data acquisition and recipe management.
Power Supply: DC 24V input (16MR/DS and 16MT/DS) with isolated power for noise immunity in industrial settings.
Environmental Rating: Operating temperature 0–55°C, humidity 5–95% (non-condensing), suitable for harsh factory floors.
