K3P-07AS

Description

MASTER-K (K200S family) CPU module; base CPU variant with 7k step program memory, 0.5 μs/step execution speed, up to 256 I/O (expandable per base).

The Polar Energy Assessment:

K3P-07AS is the standard MASTER-K200S CPU option from LS. It offers a compact program memory (≈7k steps) and is intended for small to mid-size machine control tasks where basic CPU features are sufficient. The datasheet lists core specs (execution speed 0.5 μs/step, program memory 7k steps, environmental ratings), and shows typical current consumption and compatibility notes for GM/MASTER-K module families. Use K3P-07AS where PID, HSC or RS-422/485 master features (available on other variants) are not required.

Pros

• Compact, proven CPU for small to mid-sized control tasks.
• Low internal current draw, suitable for modest power budgets.
• Simple spec set reduces configuration complexity for standard ladder projects.

Limitations

• Lacks built-in PID, RS-422/485 master, and high-speed counter features that other K3P variants provide.
• Program memory is limited compared with larger LS CPU families; plan expansion accordingly.

Typical use cases

• Small machine controllers, basic panels, and jobs where deterministic ladder logic and modest I/O are required without PID/HSC/fieldbus master needs.
