The Mitsubishi PLC Module FX1S-14MR-001 (relay output) and FX1S-14MT-001 (transistor output) are engineered for precision control in compact automation systems. With a stored program cyclic operation, this unit delivers reliable performance for applications like packaging, material handling, and simple machine control. Its ladder logic and step ladder programming support SFC-style design, while the 2K step EEPROM ensures program retention without battery backup. The module’s high-speed processing (0.55–0.7 µs for basic instructions) and rich instruction set (29 basic, 2 step ladder, and up to 116 applied instructions) make it ideal for real-time tasks. Each unit is 100% original and new, shipped with full traceability.

Additional Technical Insights
- Power Supply & Output: The FX1S-14MR-001 uses relay outputs (2A/250VAC, 2A/30VDC), while the FX1S-14MT-001 features transistor outputs (0.5A/30VDC) for high-speed switching. Both require 24VDC input power.
- Timers & Counters: Supports 32-bit up/down counters and 0.1–100 ms timers, with retentive options for critical applications.
- Data Registers: 256 general-purpose 16-bit registers (D0–D255) and 128 latched (D256–D511) for data handling; special registers (D8000–D8255) for diagnostics.
- Communication: Built-in RS-422 port for programming; optional expansion via FX1N-232-BD or FX1N-485-BD modules for Modbus or ASCII communication.
- Environmental Rating: Operating temperature 0–55°C; humidity 5–95% non-condensing; IP20 enclosure for use in clean industrial environments.
- Certifications: CE, UL, and cUL listed, ensuring compliance with global safety standards.
