LK3U-48-10AD-2DA PLC

LK3U Series

LK3U-48-10AD-2DA PLC

Model LK3U-48-10AD-2DA

LK3U-48 family selection reference with 24 digital inputs, 24 outputs and a 10 AD / 2 DA family column. High-speed output depends on the separately selected MR, MT or MRT suffix.

Product overview

This page uses LK3U-48-10AD-2DA as a selection label for the LK3U-48 size family with the manufacturer table’s 10 AD / 2 DA column. The manufacturer publishes the order rows as LK3U-48MR, LK3U-48MT and LK3U-48MRT; it does not publish this complete page label as one order code. The web table lists 24 digital inputs and 24 outputs. MR supplies 24 relay outputs and no high-speed output; MT supplies 24 transistor outputs with eight high-speed channels; MRT combines 16 relay and eight transistor outputs with eight high-speed channels. The official sources disagree on enclosure dimensions: the web table states 199×125×56 mm, while the manual shell table states 199×124×65 mm. Confirm the physical revision and complete output suffix before ordering.

Frequently asked questions

How many servo axes can the LK3U-48-10AD-2DA control via pulse output?

The published LK3U-48 MT and MRT rows provide eight high-speed transistor outputs, while MR provides none. The shared manual rates Y0–Y5 up to 200 kHz and Y6–Y7 up to 100 kHz; confirm the complete installed suffix before treating those channels as available.

What is the difference between the LK3U-48-10AD-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-48-10AD-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).
