Schneider AEG AS-B809-016

The AS-B809-016 is a PLC CPU module belonging to the Modicon series by Schneider Electric (formerly AEG), specifically designed for small and medium-sized automation systems. Powered by 230 VAC, this module is equipped with 16 PT (voltage/current) input ports, enabling direct connection to field sensors for the acquisition and control of process signals.

Key Technical Specifications

• Power Supply: 230 VAC, single-phase
• Inputs: 16 PT analog inputs, supporting common signal ranges such as 0–10 V and 4–20 mA
• I/O Expansion: Enables a maximum combination of 800 I/O points via backplane or external expansion modules
• Communication Interfaces: Supports industrial fieldbuses including Modbus-TCP, Ethernet/IP, and Profibus DP (depending on the selected communication card)
• Operating Temperature: 0 °C – 55 °C (industrial-grade wide-temperature models available as an option)
• Dimensions: Standard 19-inch rack mount, 2U width (approximately 88 mm)

Product Features

1. High Reliability: Built with industrial-grade components, it offers strong anti-interference and anti-vibration capabilities, making it suitable for harsh field environments.
2. Modular Design: The CPU is separated from I/O modules and communication cards, facilitating on-site maintenance and future upgrades.
3. Rich Communication Protocols: Compatible with multiple mainstream fieldbuses out of the box, enabling seamless connection with upper-level systems and other devices.
4. Easy Programming: Fully compatible with Schneider Electric Unity Pro (EcoStruxure Control Expert) software, supporting multiple programming languages such as ladder diagram and structured text.
5. Compact Size: With a 2U rack height, it saves cabinet space and is ideal for the layout of small and medium-sized control cabinets.

Structure and Components

• CPU Motherboard: The core processing unit responsible for program execution and logical operations.
• Analog Input Card: Provides 16 PT interfaces for voltage and current signal acquisition.
• Backplane (Rack): Used to fix the CPU and expansion cards, providing power distribution and signal routing.
• Communication Card Slot: Allows insertion of communication modules such as Ethernet, Profibus, and Modbus for network access.
• Heat Sink/Fan (Optional): Delivers additional heat dissipation under high-load or high-temperature conditions.

Typical Application Fields

• Process Control: Continuous production lines in industries such as chemical engineering, pharmaceuticals, food and beverage.
• Mechanical Automation: Motion control of packaging machinery, assembly lines, and CNC machine tools.
• Building Automation: Centralized monitoring of HVAC, lighting, and energy management systems.
• Water Treatment: Real-time monitoring and regulation of pumping stations, valves, and sensors.

Installation and Maintenance Guidelines

• Rack Mounting: Secure the module in the 2U position of a standard 19-inch rack using bolts or clips to ensure stability.
• Power Wiring: Comply with IEC 60364 standards to ensure correct phase sequence of the 230 VAC power supply and reliable grounding.
• Signal Wiring: Use shielded cables for analog input lines to avoid interference; keep signal lines separated from power lines.
• Communication Configuration: After inserting the corresponding communication card, configure network parameters (IP address, station number, etc.) in Unity Pro software and conduct on-site communication tests.
• Regular Inspection: Check the tightness of wiring connections, dust accumulation on heat sinks, and the status of module indicator lights every 6 months.
• Spare Parts Management: It is recommended to keep CPU motherboards, analog input cards, and commonly used communication cards in stock for quick replacement of faulty components.
