AEG AS-B881-001 Modicon 4-Channel Analog Output Module
- Product Introduction: This is a 4-channel universal analog output module for AEG Modicon 800 series PLC systems, engineered to convert digital control signals from the PLC CPU into precise 0-10 VDC voltage or 0-20 mA current outputs. It delivers 16-bit resolution, channel isolation, and low drift performance to drive industrial actuators like variable frequency drives (VFDs), control valves, and positioners. It is designed for applications requiring fine-tuned analog control of process parameters such as flow, pressure, and speed in industrial environments.
- Technical Specifications:
- Output Channels: 4 independent channels, each configurable for 0-10 VDC or 0-20 mA output (per-channel selection).
- Resolution: 16-bit (65536 discrete values) for both voltage and current outputs.
- Accuracy: ±0.05% FS at 25°C, ±0.1% FS over -25°C to +70°C, ensuring precise signal conversion.
- Voltage Output: 0-10 VDC, output impedance 10 Ω, maximum load current 20 mA.
- Current Output: 0-20 mA, input impedance 250 Ω, maximum load resistance 750 Ω (at 24 VDC supply).
- Isolation: 2500 VAC between channels and backplane, 1500 VAC between channels.

- Functional Features:
- 4 universal channels support both voltage and current outputs, eliminating the need for separate modules for different actuator types and reducing inventory costs.
- 16-bit resolution ensures fine control of process parameters, critical for applications like precision dosing and speed regulation of production machinery.
- High accuracy (±0.05% FS) and low drift over temperature maintain consistent output signals, minimizing process variability and improving product quality.
- Channel isolation prevents cross-talk between outputs and protects the PLC from electrical interference, ensuring stable operation in noisy industrial settings.
- Fast update rate (≤1 ms) enables real-time adjustment of outputs to dynamic process changes, such as rapid pressure fluctuations in chemical reactors.
- Wide load compatibility (750 Ω for current, 20 mA for voltage) supports long cable runs and diverse actuator types without signal degradation.
- Plug-and-play integration with Modicon 800 series PLCs, with parameters configurable via programming software for zero/span calibration and output range setting.
- Overload protection per channel prevents damage from short circuits or excessive load current, with self-recovery after fault removal.
- LED indicators for power, activity, and faults enable quick identification of issues, reducing downtime during maintenance.
- Industrial-grade components and wide temperature range ensure reliable performance in harsh environments, including extreme heat and cold.
- Application Scenarios: Widely used in process control systems for chemical manufacturing, water treatment, food and beverage production, and power generation. It drives VFDs for motor speed control in conveyor systems, control valves for flow regulation in pipelines, and positioners for precise mechanical movement in packaging machines. Suitable for any industrial application requiring Modicon PLCs to output 0-10 VDC/0-20 mA analog signals for continuous process parameter adjustment.
