AEG AS-B884-002
- Product Introduction: AEG AS-B884-002 is a high-performance 2-channel high-speed analog output module for the Modicon 800 series PLC systems, designed for precise and fast analog signal output to control industrial actuators, valves, drives and process control equipment. The module features high-resolution digital-to-analog conversion (DAC), high output speed and multiple configurable output signal types, with channel-to-channel isolation for reliable operation in noisy industrial environments. It integrates seamlessly with Modicon 800 series PLC chassis via the backplane bus, providing real-time signal output with low latency, and is a key component for closed-loop process control and motion control applications requiring high precision and fast response.
- Technical Specifications:
- Number of Channels: 2 independent high-speed analog output channels (isolated from each other and backplane bus)
- Output Signal Types: Configurable per channel – 0-10 V DC, 4-20 mA, 0-20 mA (3 signal types selectable via software)
- Resolution: 16-bit (for all signal types), 0.015% of full scale
- Accuracy: ±0.1% of full scale (25°C), ±0.2% of full scale (-25°C to +70°C)

- Functional Features:
- 2 independent 16-bit high-resolution analog output channels deliver ultra-precise signal output, ensuring accurate control of industrial actuators and process control equipment with minimal error
- <1 ms ultra-fast output update time per channel enables real-time signal adjustment for fast-dynamic process control and motion control applications, with low latency from CPU command to physical signal output
- Software-configurable output signal types (0-10 V DC, 4-20 mA, 0-20 mA) per channel adapt to a wide range of industrial actuators, valves, VFDs and instrumentation, eliminating the need for additional signal conversion modules
- High accuracy (±0.1% of full scale at 25°C) ensures consistent signal output across the entire operating temperature range, maintaining control precision in harsh industrial environments
- Channel-to-channel (1500 V AC) and channel-to-backplane bus (2500 V AC) isolation prevents electrical interference and ground loops from affecting output signal quality, ensuring reliable operation in noisy industrial environments with high-power equipment
- Built-in overload protection (short circuit for current output, overcurrent for voltage output) with auto-recovery prevents module damage from faulty wiring or short circuits in field devices, reducing maintenance downtime
- Real-time backplane bus communication with Modicon 800 series CPU (<1 ms latency) enables seamless integration into closed-loop process control systems, with instant signal adjustment based on PLC feedback
- Support for remote I/O rack integration allows the module to be mounted close to field devices, reducing signal loss and interference in long cable runs and improving control precision
- Calibration-free design with on-board self-calibration circuitry ensures long-term output accuracy without regular manual calibration, reducing maintenance costs
- LED status indicators for each channel (power, active, fault) provide instant visual feedback on channel operation status, facilitating quick on-site troubleshooting
- Rugged industrial design with wide operating temperature range (-25°C to +70°C) and industrial-grade components, ensuring stable operation in cold storage, high-temperature production lines and outdoor control stations
- Compact modular design saves space in PLC chassis and remote I/O racks, allowing integration with other digital/analog I/O modules for a complete automation solution
- Compatible with Modicon 800 series remote I/O systems, enabling distributed analog output control for large-scale industrial automation systems
