Description
Foxboro FBM04
Technical Specifications
- Model Number: FBM04
- Configuration: 4 Analog Inputs / 4 Analog Outputs
- Signal Type: 0-20 mA / 4-20 mA
- System Compatibility: Foxboro I/A Series
Functional Features
- Space Efficiency: Reduces the total module count required for paired measurement and control applications.
- Channel Isolation: Provides galvanic isolation between inputs, outputs, and the fieldbus to prevent ground loops.
- Software Configurability: Input and output ranges can be easily selected via system configuration software.
Application Scenarios
Ideal for packaged equipment, skid-mounted control panels, and localized PID control loops where space and wiring complexity are concerns.
Performance Parameters
- Response Time: Fast output update rate for responsive closed-loop control.
- Signal Fidelity: High-precision DAC and ADC ensure minimal offset and gain errors.
Material Composition
Robust components with thermal compensation to maintain accuracy across wide operating temperature ranges.
Structural Characteristics
- Compact Design: Standard FBM width with high channel density.
- Visual Feedback: Status LEDs indicate power, bus communication, and active channel states.
Working Principle
The module simultaneously digitizes incoming analog signals for monitoring and converts digital control setpoints to precise analog outputs, managing both directions of data flow over the redundant fieldbus.
Installation Requirements
Clearly label input and output terminals. Ensure the field loop power supply is correctly sized for the connected output load.
Usage Precautions
Double-check terminal assignments to prevent connecting outputs to inputs. Perform loop checks after installation to verify signal direction.
