Description
Foxboro FBM42 P0902XB
Technical Specifications
- Module Type: Combination Analog I/O Module
- Input Capacity: 8 channels of 0-20mA analog inputs
- Output Capacity: 8 channels of 0-20mA analog outputs
- Bus Interface: Foxboro Module Fieldbus
Functional Features
- Integrated Analog I/O: Combines 8 AI and 8 AO channels in one module for space efficiency.
- High Resolution: Provides precise 12-bit (or higher) resolution for accurate process control.
- Hot-Swappable Design: Supports online replacement without process interruption.
- Comprehensive Diagnostics: Reports input signal status (e.g., open wire, over-range) and output health.
Application Scenarios
Ideal for flow control loops, pressure/temperature regulation, valve positioning, and any process requiring both analog measurement and analog control output.
Performance Parameters
- Operating Temperature: 0℃ to 60℃
- Ingress Protection: IP20
- Power Requirements: Backplane powered, 24 VDC nominal via 200 Series baseplate
Material Composition
Features precision analog components with conformal-coated PCBs for stability in varying temperature and humidity conditions.
Structural Characteristics
Standard 200 Series FBM form factor. Utilizes a specialized TA with separate analog input and output terminal blocks.
Working Principle
Analog inputs are conditioned, filtered, and converted to digital values via precision ADCs. Analog outputs are generated by DACs and converted to 0-20mA current signals. Data is exchanged over the Module Fieldbus.
Installation Requirements
Install on a 200 Series baseplate. Use shielded twisted-pair cables for analog signals. Ensure proper single-point grounding of shields at the TA.
