Description
Foxboro AD202MV
Technical Specifications
- Channels: Combined analog input and analog output channels.
- Signal Types: Standard 4-20mA, 0-10V, and other industrial ranges.
- Isolation: Channel-to-channel and channel-to-ground isolation.
Functional Features
- Space Efficiency: Dual functionality reduces the total number of modules required.
- Flexible Configuration: Software-selectable input/output ranges and engineering units.
- High Immunity: Excellent rejection of common-mode and differential-mode noise.
Application Scenarios
Packaged control systems, skid-mounted equipment, and distributed I/O applications.
Performance Parameters
- Accuracy: Tight tolerance for both input measurement and output control.
- Scan Synchronization: Coordinated sampling for precise closed-loop control.
Material Composition
Robust PCB with multi-layer ground planes for superior EMI/RFI immunity.
Structural Characteristics
- Compact Footprint: Standard module width with high channel density.
- Clear Labeling: Silkscreen indicating input vs. output terminals.
Working Principle
The module simultaneously digitizes incoming analog signals for system monitoring and converts digital control values to analog outputs. Internal microprocessors manage calibration, linearization, and fieldbus communication.
Installation Requirements
- Separate analog signal cables from high-voltage power cables in the wiring duct.
- Ground the shield at the module baseplate for optimal noise rejection.
Usage Precautions
- Double-check terminal assignments to prevent connecting outputs to inputs.
- Perform a loop check and calibration verification after installation.
