Compact Machine Automation Solution – Mitsubishi FX1S-20MT-001 | MELSEC FX1S Series
Where This Product Is Used
The Mitsubishi FX1S-20MT-001 is a high-reliability compact PLC widely deployed across demanding industrial environments. Its transistor (NPN sink) output and DC power architecture make it the preferred controller for applications requiring fast, noise-immune digital switching:
- Packaging Machinery – Precise sequencing of film feeders, sealing jaws, and label applicators at high cycle rates
- Conveyor & Material Handling – Multi-zone belt control, diverter logic, and sensor-triggered sorting systems
- Machine Tools & CNC Peripherals – Spindle interlocks, tool-change sequencing, and coolant pump management
- Textile & Printing Equipment – Tension control, register mark detection, and web-break response
- Building Automation & HVAC – Fan/pump scheduling, damper positioning, and alarm annunciation panels
- Food & Beverage Processing – Wash-down-adjacent control panels with compact footprint requirements
- OEM Control Panels – Space-constrained enclosures where DIN-rail density is critical

Why Engineers Specify This Model
- Transistor Output for High-Speed Applications – Unlike relay-output variants, the MT suffix delivers sub-millisecond switching, enabling pulse-train outputs for stepper/servo drives and high-frequency counter inputs.
- DC-Only Power Architecture – Eliminates AC noise coupling in sensitive sensor environments; simplifies 24 VDC panel wiring and reduces transformer requirements.
- Proven MELSEC FX1S Platform – Backed by Mitsubishi Electric’s decades of FX-series reliability data; extensive installed base ensures long-term spare-parts availability.
- Compact DIN-Rail Footprint – Fits tight enclosures where larger PLCs cannot be accommodated, without sacrificing programming capability.
- GX Developer / GX Works2 Compatible – Seamless integration with Mitsubishi’s standard engineering software ecosystem.

Application-Specific FAQ
Q: Can the FX1S-20MT-001 control a stepper motor directly?
A: Yes. The transistor outputs support pulse-train (PLS/PLSY instructions) up to 100 kHz, making it suitable for open-loop stepper control without an external pulse generator.
Q: Is the FX1S-20MT-001 compatible with FX2N expansion modules?
A: No. The FX1S is a standalone unit and does not support expansion I/O modules. For expandable systems, consider the Mitsubishi FX3U or FX5U series.
Q: What is the difference between FX1S-20MT-001 and FX1S-20MR-001?
A: The MT suffix denotes transistor (DC) output; MR denotes relay output. Transistor outputs are faster and suited for pulse outputs and high-cycle applications; relay outputs handle higher voltages and AC loads.
Q: Can I use GX Works3 to program this PLC?
A: No. GX Works3 supports FX5 series and iQ-R/iQ-F platforms only. Use GX Works2 or GX Developer for FX1S programming.
Q: What is the warranty on units sourced from Konmask.com?
A: All units carry a 12-month warranty against manufacturing defects. Contact [email protected] for warranty claims and RMA procedures.
