AEG AS-B883-01 Modicon 4-Channel Analog Output Module

  • Product Introduction: This is a 4-channel universal analog output module for AEG Modicon 800 series PLC systems, specially designed to convert the digital control signals of the PLC CPU into standard analog signals (4-20 mA DC/0-10 VDC) to drive industrial field actuators such as frequency converters, electric regulating valves, and servo drivers. It features 16-bit high-resolution D/A conversion, independent channel configuration, and high output stability, and is an essential analog control component for Modicon PLC systems to realize continuous regulation of industrial process parameters.
  • Technical Specifications:
    • Output Channels: 4 independent channels, each channel configurable for 4-20 mA DC current output or 0-10 VDC voltage output (one-to-one configuration).
    • Resolution: 16-bit for both current and voltage output, 65536 discrete output values for precise analog control.
    • Output Range Accuracy: ±0.05% of full scale (FS) at 25°C for 4-20 mA; ±0.1% FS at 25°C for 0-10 VDC; total error ≤0.2% FS over -25°C to +70°C.
    • Output Drive Capacity: 4-20 mA channel: maximum load resistance 750 Ω; 0-10 VDC channel: maximum load current 20 mA, output impedance ≤10 Ω.

    • LED Indicators: Power (green), channel output status (yellow per channel), fault (red), overcurrent alarm (orange per channel).
    • Compatibility: Fully compatible with Modicon 800 series PLC CPUs (AS-P800 series, AS-P890 series), support IEC 61131-3 standard programming.
  • Functional Features:
    • 4 independent universal analog output channels support one-to-one configuration of 4-20 mA current or 0-10 VDC voltage output, adapting to different driving requirements of industrial field actuators, and realizing flexible matching with frequency converters, regulating valves and servo drivers without additional signal conversion modules.
    • 16-bit high-resolution D/A conversion ensures the precision of analog output signals, the output error is as low as ±0.05% FS, and the fine adjustment of industrial process parameters (such as flow, pressure, speed) is realized, improving the control precision of the process control system.
    • Channel-to-channel and channel-to-backplane high-voltage isolation effectively suppresses industrial field electromagnetic interference, prevents ground loop interference between different actuators, and ensures the stability of analog output signals and the safety of the PLC system.
    • Fast output update rate (≤1 ms per channel) realizes real-time response of analog output to PLC digital control signals, meeting the high real-time requirements of fast dynamic adjustment of industrial process parameters, and ensuring the synchronicity of control system regulation.
    • Built-in self-recovering overload protection for each channel effectively protects the module from damage caused by short-circuit and overcurrent of the actuator side circuit, and the overcurrent alarm LED indicator realizes visual monitoring of channel fault status, facilitating quick troubleshooting.
    • High output drive capacity adapts to different load resistance/current requirements of field actuators, the 4-20 mA channel can drive actuators with a maximum load resistance of 750 Ω, and the 0-10 VDC channel has low output impedance, ensuring no signal attenuation during long-distance transmission.
    • Plug-and-play integration with Modicon 800 series PLC chassis, the module parameters can be configured online through the PLC programming software, no additional hardware adjustment is required, and the channel output range and zero/span calibration can be completed through software, simplifying system debugging.
    • Wide operating temperature range and industrial-grade component selection ensure the module can work stably in extreme industrial environments such as high temperature, low temperature and high humidity, and the mean time between failures (MTBF) is more than 200,000 hours, reducing system maintenance costs.
    • Low power consumption design does not increase the overall power load of the PLC chassis, and the 24 VDC backplane power supply eliminates the need for additional power supply wiring, simplifying the system wiring structure and reducing installation space.
  • Application Scenarios: Widely used in industrial process control systems in the fields of petrochemical, chemical, water treatment, food and beverage, mechanical processing and building automation. It is the core analog control component for Modicon PLC systems to drive frequency converters (speed regulation), electric regulating valves (flow/pressure regulation), servo drivers (position/speed regulation), and electric actuators (valve opening/closing regulation) in oil refinery distillation processes, chemical reactor control, water treatment plant sewage treatment, and food production line mixing control, and is suitable for all industrial occasions that require Modicon PLC to output standard analog signals and realize continuous regulation of field actuators.
