Description
Foxboro FBM201 P0914SQ
Technical Specifications
- Module Type: Analog Input Module
- Input Capacity: 8 isolated channels
- Input Range: 0 to 20 mA DC
- Bus Interface: Foxboro Module Fieldbus
Functional Features
- High-Precision Conversion: Utilizes Σ-Δ ADCs for high-resolution, noise-immune signal acquisition.
- Channel Isolation: Each channel is electrically isolated from others and ground to prevent ground loops.
- Configurable Filtering: Supports adjustable integration times and rate-of-change limits.
- Hot-Swappable Maintenance: Enables online replacement to maximize process uptime.
Application Scenarios
Widely used for monitoring pressure, flow, level, and temperature transmitters across petrochemical, power, and water treatment industries.
Performance Parameters
- Operating Temperature: -40℃ to +70℃
- Power Dissipation: 3W maximum
- Ingress Protection: IP20
Material Composition
Features conformal-coated electronics housed in a compact, robust enclosure rated for harsh G3-class environments.
Structural Characteristics
Measures 10.4 cm x 4.5 cm x 11.4 cm and weighs 0.284 kg. Connects to field wiring via a dedicated Terminal Assembly (TA).
Working Principle
Incoming 0-20mA signals are isolated, filtered, and digitized by Σ-Δ converters. The module processes the data and transmits it to the controller via the redundant 2 Mbps Module Fieldbus.
Installation Requirements
Install on a 200 Series baseplate. Ensure adequate cabinet ventilation and maintain ambient temperatures within the specified range.
Usage Precautions
Do not exceed the 20mA input limit. Verify TA wiring matches the channel configuration. No module calibration is required.
