Lingkong LK3U‑24‑6AD‑2DA PLC Controller – 24 I/O, Analog, RS485

by

Intro Summary
The LK3U‑24‑6AD‑2DA is a cost-effective Mitsubishi‑compatible PLC: 24 I/O, analog channels, pulse support—perfect for industrial automation.

Product Overview
The LK3U‑24‑6AD‑2DA is an industrial-grade programmable controller from Lingkong, offering 12 digital inputs, 12 digital outputs, plus 6 analog inputs and 2 analog outputs . Available in relay (MR) or transistor (MT) output versions, it supports high-speed pulse I/O, RS485/RS232 communication, and an optional real-time clock. Compact and reliable, it integrates with GX Works/MX, supports HMI/text-screen, and is compatible with Mitsubishi FX3U series. Ideal for machine control, weighing, data logging, and automation tasks.

How to Use

  1. Mount on DIN rail and power with 24 V DC.
  2. Wire digital I/O, analog I/O, and communication ports per label.
  3. Connect RS232/485 or HMI panel if needed.
  4. Use GX Developer or GX Works to program logic, configure analog scaling, and set high-speed pulse parameters.
  5. Deploy and test I/O functionality.
    Tips: match MR/MT version to your output type. Include proper earthing. Use RS485 for networked PLCs.
