The A3NCPUR21 CPU module from Mitsubishi is engineered specifically for complex control systems. Optimized for high efficiency, it can handle substantial programming tasks with a maximum capacity of 30k steps for both main and sub-sequence programs, facilitating advanced task management. With a memory capacity reaching 448k bytes, this module is capable of storing extensive program data, contributing to its powerful performance capabilities.
The unit's physical dimensions measure 250 mm in height, 79.5 mm in width, and 121 mm in depth, making it compact enough for integration into tight spaces while weighing just 0.95 kg. It operates efficiently within temperatures ranging from 0°C to 55°C, which ensures reliability in various environmental conditions.
The A3NCPUR21 utilizes a sequence program method for control, allowing flexibility in programming through a dedicated language suited for sequence control with relay symbols and logical symbolic languages. Its selectable I/O control methods include both refresh and direct modes, promoting tailored application requirements. The processing speed ensures that sequence instructions are executed quickly, at rates of 1.0 to 2.3 microseconds per step, depending on the mode. Additionally, the system can tolerate momentary power interruptions of up to 20 milliseconds or less, which aids in maintaining operational continuity during transient events. The module consumes 1.95A from a 5 VDC power supply, reflecting its energy efficiency in demanding applications.
