K4P-15AS

Description

MASTER-K series CPU module with ≈15k program steps and mid-range performance for small-to-medium control tasks. Fits the K4/K series family for LS/MASTER controllers and supports typical I/O expansion up to the family limits.

The Polar Energy Assessment:

The K4P-15AS is a MASTER-K (K-series) CPU option intended when you need more program memory than the smallest K modules but still want a compact, cost-efficient controller. It comes with ~15k user program steps and support for up to several hundred I/O points depending on rack and expansion choices; it’s commonly used in mid-size machines and compact plant controllers that require deterministic ladder execution without the complexity of higher-tier CPUs. Confirm exact I/O limits and the CPU slot rules in the MASTER-K family manual when building the rack.

Pros

• Good program memory for modestly complex ladder programs (≈15k steps).
• Compact and cost effective for OEM and mid-size applications.
• Fits standard MASTER-K slot rules and expansion topology.

Limitations

• Not a high-end CPU; if you want larger programs, heavy communications stacks or extensive motion features, step up to larger families.
• Verify peripheral/comm feature set for your exact SKU variant before specifying.

Typical use cases

• Machine logic, HVAC/chiller local controllers, small process loops, and brownfield retrofits where moderate program size and I/O expansion are required.
