AEG ALU821 Logic Arithmetic Unit Module
- Product Introduction: It is an arithmetic logic unit module matched with AEG PLC, which is mainly used to perform high‑speed arithmetic operations (addition, subtraction, multiplication, division) and logic operations (AND, OR, NOT) on the data in the PLC system, and improve the data processing capability of the system, especially suitable for occasions that require complex data calculation and logic judgment.
- Technical Specifications:
- Operation Precision: 16‑bit fixed‑point arithmetic, supporting integer and BCD code operation.
- Operation Speed: Arithmetic operation ≤1 μs per instruction, logic operation ≤0.5 μs per instruction.
- Interface: Compatible with the AEG Modicon backplane bus, data transmission rate up to 1 Mbps.
- Power Supply: 24 VDC, power consumption of 2 W.
- Isolation: 1500 VDC isolation between the arithmetic unit and the system bus.
- Operating Temperature: -20°C to +60°C; Dimensions: 100mm × 160mm × 50mm (W×H×D).
Detailed content
- Functional Features:
- Supports parallel operation, which can perform multiple arithmetic/logic operations at the same time and improve the data processing efficiency of the system.
- Built‑in data register and accumulator, which can temporarily store intermediate data during operation and ensure the accuracy of operation.
- It has an operation error detection function, which can identify errors such as overflow and zero division, and trigger an alarm signal to the CPU.
- It can be cascaded with multiple ALU modules to expand the parallel operation capability and meet the needs of large‑scale data processing.
- It is seamlessly compatible with AEG Modicon series CPUs, and no additional configuration is required for plug‑and‑play.
- Application Scenarios: It is used in industrial control systems that require complex calculations, such as batching control in the chemical industry, speed regulation calculation of frequency converters in the power industry, weight measurement and calculation in the logistics sorting system, and position control algorithm operation in CNC machine tools, to provide data support for the precise control of the system.
