Mitsubishi Electric Q2ASCPU-S1 Programmable Logic Controller

The Mitsubishi Electric Q2ASCPU-S1 is a PLC CPU module in the MELSEC-A/QnAS family that delivers centralized, high-performance control for large production lines, process plants, and complex machinery. It supports up to 60K steps of program capacity, up to 1024 I/O points (8192 device points internal), stored program cyclic execution, and a 5 V DC supply drawing about 300 mA, with an operating range of 0–55 °C and IP20 protection. The module mounts on a QnAS rack/base unit, includes a built-in real-time clock, RUN/STOP indicators, multi-file program handling (up to 60 files), and compatibility with multiple network and communication modules. Typical applications include material handling, packaging lines, and other automated manufacturing and process-control systems requiring high I/O counts and reliable coordination. Common replacements include Mitsubishi Q02HCPU and Q06HCPU.
