Product overview

The LK3U-32-10AD-2DA is a plc model in the LK3U Series, offering 16 DI / 16 DO (32 pt) with 10 (Default 0-10V, configurable to 0-20MA or NTC10/50K temperature) analog inputs and 6 channels 200K, 2 channels 100K (MR type without high-speed output) pulse output capability. LK3U is the flagship compact PLC series with 3 communication ports, 6+2 high-speed pulse outputs, and 4–10 analog inputs.

As part of the LK3U Series, this model shares the series' core platform — DC24V power, IP65 protection, and GX Developer / GX WORKS2 programming environment. Output types include MR (relay), MT (transistor), and MRT (mixed) where indicated.

Compared to other models in the LK3U Series, the LK3U-32-10AD-2DA sits between the LK3U-14-4AD-2DA (lower I/O count) and the LK3U-80-10AD-2DA (higher I/O count). For projects with fewer I/O points, a smaller model may reduce cost; for projects expected to scale, a larger model provides headroom without CPU replacement.

Retrofit and replacement projects

Selection notes

Confirm total I/O points (DI + DO) and required output type (MR / MT / MRT).
MT or MRT output type required for pulse output — MR type has no high-speed output.
NCAN and ECAN are mutually exclusive — choose one per CPU.
Check cabinet depth: LK3U is 56 mm deep.

Frequently asked questions

How many servo axes can the LK3U-32-10AD-2DA control via pulse output?

The LK3U series provides 6×200KHz + 2×100KHz high-speed pulse output channels, supporting up to 8 independent motion axes. MT or MRT output type is required — MR type cannot generate high-speed pulses.

What is the difference between the LK3U-32-10AD-2DA and adjacent models in the LK3U series?

Adjacent models in the LK3U series differ primarily in I/O point count and analog input channels. The suffix convention (e.g. 14-4AD-2DA) indicates total I/O points, analog input channels, and analog output channels. Choose the model with sufficient I/O and analog capacity for your application.

What programming software is used with the LK3U-32-10AD-2DA?

All LK PLC series use GX Developer or GX WORKS2 programming software. The connection is via RS232 serial port (or USB-to-RS232 adapter).
