Q00JCPU

The Q00JCPU is a basic CPU module belonging to the MELSEC-Q series of programmable logic controllers, designed for industrial automation applications where compact, reliable control is essential. This all-in-one unit combines a single-processor CPU, a 5-slot base unit, and a built-in power supply into one integrated package, accepting a wide-range AC input of 100–240 VAC at 50/60 Hz — making it suitable for use worldwide. Its stored-program cyclic operation and refresh-mode I/O processing deliver consistent, deterministic control performance across a broad range of machine and process applications.Q00JCPU

With a program capacity of 8K steps (58 KB) and support for up to 256 I/O points, this controller handles small-to-mid-scale automation tasks efficiently. The onboard RS-232 interface via a 9-pin D-Sub connector enables straightforward programming and monitoring, while support for multiple programming languages — including Ladder Diagram, Structured Text, Function Block Diagram, and SFC — gives engineers flexibility in how they develop and maintain control logic. The integrated flash ROM eliminates the need for a separate memory backup battery for program storage.

This particular unit Q00JCPU is offered in used and tested condition, meaning it has been powered up and verified for operational functionality prior to sale. Sourcing a tested pre-owned module like this one is a practical, cost-effective path for facilities looking to replace a failed controller, maintain a spare-parts inventory, or commission a retrofit project without the lead times often associated with new industrial automation components. Every effort is made to ensure the module ships ready for installation.Q00JCPU

The MELSEC-Q platform is known throughout the automation industry for its modular architecture, broad ecosystem of compatible I/O and communication modules, and long field service history. Whether you are maintaining an existing production line or building a new control panel around a proven platform, this controller offers dependable performance backed by a well-documented instruction set and an extensive support community.Q00JCPU
