YKHMI 2.8″ All‑in‑One HMI + PLC MM‑9MR‑4MT‑FE280‑FX‑A

by


Compact 2.8″ touchscreen HMI + Mitsubishi‑compatible PLC for industrial automation, perfect for small machine control.

Product Overview
The MM‑9MR‑4MT‑FE280‑FX‑A combines a 2.8‑inch resistive touch display and an integrated FX‑series PLC core compatible with Mitsubishi FX1S. It features 9 digital inputs, 4 transistor outputs, built‑in RS232/RS485 communications, and supports YKBUI LDER V5.3 for HMI and WPLSoft for PLC programming. Its compact footprint makes it ideal for panel mounting on packaging machines, conveyors, small processing equipment, and temperature control systems. Key selling points: all‑in‑one integration, cost‑effective, easy setup, industrial‑grade reliability.

How to Use

  1. Mount the unit in a 92×70 mm cut‑out, secure with rear clamps.
  2. Connect 24 V DC power, wiring inputs/outputs per manual.
  3. Install USB‑to‑MiniUSB cable to PC.
  4. Use Mitsubishi WPLSoft to write PLC logic, download via USB.
  5. Use YKHMI’s YKBUI LDER V5.3 to design HMI screens, upload.
  6. Test I/O in run mode, monitor via HMI.
    Tips: label wires clearly, back up both PLC and HMI projects, keep firmware up to date. Ensure proper grounding and isolation from high‑voltage noise.

User Review Summary
Actual user feedback for similar FE280 models highlights easy setup and reliable operation. Pros: integration reduces panel space, solid build, cost‑effective. Cons: limited I/O count, UI graphics basic, manual sparse, need trial to master software.

Comparison with Competing Products
Allen‑Bradley Micro800+PanelView 800: higher graphics, more I/O, but cost ≈ $800 and steeper learning.
Delta DOP‑W series: 4.3″ HMI paired with separate Delta PLC; more I/O and features, but requires two devices and extra wiring.
Kinco GL070‑MT: similar 7″ integrated but larger footprint and price ≈ $250. MM‑9MR‐4MT is best for budget 2.8″ needs.
