Lingkong LK3U‑32‑10AD‑2DA PLC Controller with Weighing & CAN

by

Intro Summary
Compact industrial-grade PLC supporting analog I/O, weighing channels, RS‑485/CAN, ideal for automation systems.

Product Overview
The Lingkong LK3U‑32‑10AD‑2DA is a versatile PLC controller compatible with Mitsubishi FX3U-style systems. It offers 16 discrete inputs, 16 discrete outputs, 10 analog inputs (10AD) adjustable for temperature or weight, plus 2 analog outputs (2DA), RS‑232 and optional RS‑485 or CAN communication. A built‑in run/stop switch and status LEDs make diagnostics intuitive. It’s designed for industrial automation applications requiring precise control and analog measurement.

How to Use

  1. Mount securely in a control cabinet and wire 24 V DC power supply.
  2. Connect discrete inputs/outputs as labeled.
  3. For analog tasks (e.g., thermocouples or load cells), calibrate the AI channels via software.
  4. Link to a PC over RS‑232/RS‑485 or network with CAN for programming using FX3U-compatible software.
  5. Set RUN mode via onboard switch.
  6. Monitor status through LEDs. Tip: ensure proper grounding and shielding on analog lines to minimize noise.

Some mention simple interface and good value. A few point out limited official documentation—recommended to rely on suppliers or community resources.

Comparison with Competing Products
– Mitsubishi FX3U‑10AD PLC: professional-grade and fully supported, but more expensive (~¥30,000+). Lingkong provides FX3U compatibility at lower cost.
– LK3U‑32‑AD‑DA variant: similar core I/O but without weighing-specific functions—better for pure discrete control, less suitable for load-cell tasks.
– ZK3U‑32‑10AD‑2DA: adds axis pulse output but may lack FX3U-specific features.
