LK3U Series
Model LK3U-48-10AD-2DA
The LK3U-48-10AD-2DA is a plc in the LK3U Series, featuring 24/24 (48 pt), 24/24 (48 pt) analog inputs, and 24/24 (48 pt) pulse output.
The LK3U-48-10AD-2DA is a plc model in the LK3U Series, offering 24/24 (48 pt) with 24/24 (48 pt) analog inputs and 24/24 (48 pt) 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-48-10AD-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.
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.
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.
All LK PLC series use GX Developer or GX WORKS2 programming software. The connection is via RS232 serial port (or USB-to-RS232 adapter).
