Product Description

Foxboro FBM216 P0917TN

Overview

The FBM216 is typically an 8-channel module with redundancy support and HART input functionality. It processes HART signals from field devices, enables communication with smart transmitters, and collects/processes relevant data in industrial automation control systems.

Functional Features

Channel Configuration: 8 channels for connecting multiple field devices to achieve data collection from multiple measurement points.
Redundancy Function: Supports redundant configuration to enhance system reliability and stability. When one module fails, the redundant module continues operation to ensure system normalcy.
HART Communication: As a HART input module, it communicates with HART-protocol smart transmitters, receives/processes digital signals from transmitters, and obtains rich device information (e.g., process variables, device status, diagnostic data).
Electrical Isolation: Each channel uses electrical and optoelectronic isolation technologies to effectively prevent external electrical interference, improve system anti-interference capability, and protect the module and other devices from electrical faults.
Overcurrent Protection: The I/O circuit adopts overcurrent protection technology (no fuse required), enhancing module safety and stability by protecting the module and connected devices in overcurrent conditions.

Technical Parameters

Input Type: Supports HART signal input.
Number of Channels: 8 channels.
Redundancy Feature: Equipped with redundancy.
Communication Protocol: Follows HART protocol for communication with field devices compliant with this protocol.
Electrical Characteristics: Uses electrical and optoelectronic isolation technologies; I/O circuit with overcurrent protection; operating voltage typically around 24VDC.

Working Principle of Foxboro FBM216 P0917TNI. Functional Overview

The Foxboro FBM216 (P0917TN) is a Fieldbus Module in Emerson's DeltaV control system, belonging to the Analog Input (AI) module. Its core function converts analog signals (e.g., 4-20mA current, 0-10V voltage) from field devices (e.g., pressure transmitters, temperature sensors) into digital signals and transmits them to the DeltaV controller. It also supports HART protocol communication for two-way data interaction with smart instruments.

II. Working Principle Architecture

Signal Acquisition and Input Processing

Input Signal Types:
Supports 8-channel differential analog input, compatible with:

4-20mA current signals (standard industrial signals);
0-5V, 0-10V voltage signals;
Temperature signals from thermocouples (e.g., J, K, T types) and resistance thermometers (RTD, e.g., PT100).

Signal Conditioning:
Input signals first enter the module via terminal blocks (e.g., TBX series), processed by signal filtering (to eliminate high-frequency interference) and amplification/attenuation circuits, ensuring signal amplitude matches the input range of the analog-to-digital converter (ADC)

Analog-to-Digital Conversion (ADC) and Data Processing

ADC Core:
The module integrates a high-resolution 16-bit ADC to convert analog signals into digital quantities (binary data). The conversion accuracy reaches ±0.05% of the full scale, ensuring data collection accuracy.
Sampling and Quantization:
Samples analog signals at a preset frequency (e.g., multiple times per second), discretizes continuous signals into digital values via quantization algorithms, and reduces noise interference through digital filtering (e.g., average filtering, Kalman filtering).

HART Communication Protocol Integration

HART Protocol Mechanism:
HART (Highway Addressable Remote Transducer) is a communication protocol superimposing digital signals on analog signals, using frequency shift keying (FSK) technology:

Analog signals (4-20mA) transmit real-time process variables;
Digital signals (1200bps FSK signals) superimposed on analog signals transmit device parameters, diagnostic information, etc.

HART Implementation in the Module:
Each channel is equipped with a dedicated FSK modem to support two-way communication with HART smart instruments (e.g., transmitters):

As the master, the module actively queries instrument data (e.g., range, calibration values);
Receives digital information (e.g., device status, fault codes) from instruments and interacts with the DeltaV system database

Electrical Isolation and Anti-Interference Design

Isolation Technology:
The module uses optoelectronic or magnetic isolation technology to achieve:

Electrical isolation between input channels;
Isolation between channels and module logic circuits/grounding systems.

Anti-Interference Function:
Isolation design effectively suppresses common-mode interference, ground-loop currents, etc., ensuring stable operation in industrial environments (e.g., strong electromagnetic interference, voltage fluctuations)

Data Transmission and System Interaction

Communication with DeltaV Controller:
The module transmits digitized signals to the controller via the DeltaV system's fieldbus (e.g., ControlNet or EtherNet/IP). The communication process follows DeltaV protocol, supporting real-time data updates and two-way command transmission (e.g., remote module parameter configuration).
Status Feedback and Diagnosis:
LED indicators (e.g., PWR, COM, CHx) on the module front panel display working status in real time. Internal diagnostic circuits monitor channel anomalies (e.g., signal out-of-range, open circuit) and report fault information to the DeltaV operator station.

Power Supply and Power Consumption Management

Power Supply Mode:
Uses 24VDC redundant power input, supporting voltage fluctuation within ±5% to ensure continuous operation under unstable power supply.
Power Consumption Control:
The module integrates low-power circuits with a maximum power consumption of approximately 7W. The heat dissipation design meets the industrial environment temperature requirement of -20°C to +70°C.

III. Summary of Key Technical Features and Working Logic

Technical Dimension	Working Principle Highlights
Signal Conversion Flow	Analog input signal → Signal conditioning → 16-bit ADC conversion → Digital filtering → Bus transmission to controller
HART Communication Mechanism	4-20mA analog signal superimposed with FSK digital signal for two-way data interaction, compatible with smart instrument parameter configuration
Isolation and Reliability	Channel electrical isolation + anti-interference design to ensure signal stability in industrial environments and reduce external interference on data collection
System Integration Logic	As an I/O node of the DeltaV system, forms a closed-loop control with the controller and operator station via fieldbus, supporting real-time data monitoring and fault diagnosis

IV. Principle Differences from Similar Modules (e.g., FBM215)

The FBM215 (P0917TQ) is an analog output (AO) module, core function: converting digital signals into analog signals (4-20mA or superimposed with HART signals) and outputting to actuators.
The FBM216 (P0917TN) is an analog input (AI) module, focusing on signal acquisition and digitization. The two differ essentially in signal flow, circuit design (e.g., ADC vs. DAC), and application scenarios.

Application Fields

Widely applied in industrial automation control systems of power, petroleum, chemical, natural gas, metallurgy, cement, papermaking, mining, light textiles, food, medicine, and other industries. It connects field devices like smart transmitters to achieve precise measurement, data collection, and transmission of process variables, providing accurate information for control systems to monitor and make control decisions.
