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.
