Schneider AEG AS-BADU-214

The AS-BADU-214 is an analog input module launched by Schneider Electric (formerly AEG), specially designed for Modicon PLC series (e.g., M340, Quantum). It achieves high-speed and reliable communication with PLC master stations via backplane insertion, ideal for scenarios like process control, monitoring and data acquisition.

Key Technical Specifications

• Input type: 0-10 V DC, ±10 V DC (voltage); 0-20 mA DC (current, optional)
• Resolution: 12-bit (corresponding to 0-4095 counts)
• Sampling rate: Up to 1 kS/s per channel
• Input impedance: ≥10 MΩ (voltage) / ≥250 Ω (current)
• Power supply: 24 V DC (backplane powered)
• Operating temperature: 0 °C – +55 °C (industrial grade)
• Protection class: IP20 (for indoor cabinets)
• Communication protocol: Compliant with Modicon PLC backplane bus protocol (Ethernet/IP, Modbus TCP optional)

Product Features

1. High precision: 12-bit resolution combined with low-noise front-end enables accurate capture of process signals
2. Multiple input ranges: Optional voltage or current input to meet requirements of different on-site sensors
3. Modular design: Plug-and-play with hot-swappable support, facilitating quick on-site replacement or capacity expansion
4. Diagnostic function: Built-in alarm for channel short circuit, open circuit, overvoltage/undervoltage to simplify fault location
5. Strong compatibility: Compatible with all Schneider Modicon PLC series and supports standard backplane slots

Structure & Components

• Backplane connector: Provides 24 V DC, ground wire and data bus
• Analog input card: Internally integrates 8-channel analog front-end circuits, A/D converters, buffer and filtering units
• Diagnostic indicator lights: Each channel is equipped with LED indicator to display channel status (normal/fault)
• Enclosure: Metal housing compliant with IEC 60529 IP20 protection standard

Typical Application Fields

• Process industry: Signal acquisition of temperature, pressure, flow rate in continuous production processes (chemical, petroleum, pharmaceutical, etc.)
• Energy management: Current and voltage monitoring in power plants and distribution networks
• Building automation: Sensor connection for HVAC systems
• Laboratory & R&D: Test platforms requiring high-precision analog signal acquisition
