AEG AS-B872-100 2-Channel Analog Output Module

  • Product Introduction: This is a 2-channel analog output module of the AEG Modicon 800 series PLC, which converts the digital control signals generated by the PLC CPU into standard analog voltage/current signals to drive industrial field actuators such as electric regulating valves, frequency converters, and servo drivers. It is a key interface module for the PLC system to realize continuous and precise control of industrial processes.
  • Technical Specifications:
    • Output Channels: 2 independent isolated analog output channels, each channel can be configured independently.
    • Output Signal Types: 0-5 VDC, 0-10 VDC (voltage output); 4-20 mA, 0-20 mA (current output), software configurable.
    • Resolution: 12 bits; Output Accuracy: ±0.1% of full scale at 25°C, ±0.25% over the entire operating temperature range.

Detailed content

    • Output Load Capacity: Voltage output ≥1 kΩ; Current output ≤500 Ω.
    • Conversion Time: ≤1 ms per channel, supports synchronous output of multiple channels.
    • Isolation: 2500 VAC isolation between channels, between channels and the backplane bus, and between channels and power supply.
    • Power Supply: 24 VDC, power consumption of 2.5 W.
    • Operating Temperature: -25°C to +70°C; Protection Rating: IP20; Dimensions: 80mm × 160mm × 50mm (W×H×D).
  • Functional Features:
    • Each channel supports independent signal type and range configuration through software, without hardware jumpers, which is convenient for on-site debugging and configuration.
    • Built-in output signal calibration function, supports online zero and span calibration through PLC programming software, ensuring long-term output accuracy of the module.
    • The module is equipped with LED status indicators for each channel, displaying output normal, overrange and fault status, which is convenient for quick troubleshooting of field actuator faults.
    • It has output short-circuit and overcurrent protection functions, which can automatically limit the output current when the load is short-circuited to protect the module and field equipment.
    • Supports hot swapping function, which can replace the module without shutting down the PLC system, effectively reducing the downtime of the production line.
    • The high-precision D/A conversion chip ensures the linearity and stability of the output signal, and the output signal has low drift, which is suitable for long-term continuous industrial process control.
    • Fully compatible with AEG Modicon 800 series PLC backplane bus, can be flexibly combined with analog input modules, digital I/O modules to form a complete process control system.
  • Application Scenarios: Widely used in industrial process control systems that require precise analog quantity output, such as chemical plant reactor temperature and pressure regulation, power plant steam flow control, water treatment plant water level and flow adjustment, and food processing production line material feeding speed control. It is also used to drive frequency converters in mechanical equipment to realize stepless speed regulation of motors, and to control electric regulating valves in pipeline systems to adjust the flow of media, and is suitable for all industrial occasions that require continuous control of field actuators.
