The Mitsubishi A3HCPU functions as a CPU module designed to meet the needs of sophisticated control applications. With a capacity for 2048 I/O points, the module offers flexibility in system design. Its selectable I/O control mode can be set to either refresh or direct methods, depending on operational requirements.
This module utilizes a specialized programming language intended for sequence control, promoting straightforward logic and relay symbol implementations. The constant scanning ability is adjustable, allowing users to configure it between 10 milliseconds and 190 milliseconds in 10-millisecond increments. This flexibility enables precise control timings tailored to specific applications.
The internal memory capacity of the A3HCPU reaches a maximum of 144k bytes, which can accommodate extensive programming needs. The program capacity for both the main sequence and sub-sequence programs is capped at 30,000 steps each, while it allows for 58,000 steps in microcomputer programs. Processing speeds for sequence instructions depend on the mode; direct mode operates at 0.2 to 0.2 microseconds per step, whereas refresh mode operates from 0.2 to 0.4 microseconds per step.
Power consumption for the internal operation is rated at 3.0A using a 5 VDC supply. The unit's dimensions are measured at 250 mm in height, 79.5 mm in width, and 121 mm in depth. It weighs 0.9 kilograms, making it suitable for various applications without adding excessive bulk or weight. The A3HCPU is built for stored programs and repeat operations, ensuring reliable performance in the control systems it governs.
