Description
Foxboro FBM216 P0922VV
Technical Specifications
- Input Type: 0-20mA with HART Digital Communication
- Input Channels: 8 redundant channels
- Communication Protocol: Redundant 2 Mbps Module Fieldbus
- Hardware Code: P0922VV
Key Features
- Hardware-Level Redundancy: Eliminates single points of failure by providing redundant input paths for critical measurements.
- Smart Device Integration: Supports HART communication for advanced diagnostics and device management.
- Seamless Failover: Automatically switches to the backup channel upon primary channel failure without process disruption.
- Integrated Diagnostics: Provides detailed redundancy status and channel-level health monitoring.
Application Scenarios
Essential for safety-critical and high-value process control in refineries, nuclear power, and offshore platforms where measurement reliability is paramount.
Performance Parameters
- Operating Temperature: 0°C to 60°C
- Storage Temperature: -40°C to 85°C
- Power Supply: 24 VDC redundant backplane supply
Material Composition
Features a rugged industrial enclosure with conformal-coated internal circuitry to withstand harsh environments.
Structural Characteristics
Standard 200 Series FBM single-width design. Connects to the backplane via a secure rear interface and utilizes a designated Terminal Assembly for redundant field wiring.
Operating Principle
Continuously monitors both primary and redundant input channels. The system automatically selects the valid signal and seamlessly transitions to the backup channel if a fault is detected, while simultaneously extracting HART digital data.
Installation Requirements
Install on a Foxboro 200 Series baseplate. Redundant configuration must be strictly defined in the system software. Ensure redundant field wiring is identical and properly routed.
Usage Precautions
Verify that the redundancy logic is correctly configured in the DCS. Ensure both primary and redundant field connections are secure and correctly polarized.
