FOXBORO FBM216 P0917TN Redundant HART®CommunicationInput Module

FOXBORO FBM216 P0917TN Redundant HART®CommunicationInput  Module

INTRODUCTION

The FBM216bHARTCommunication Redundant Input Interface Module contains eight individually isolated input channels. It supports any mix of standard 4 to 20 mA devices and HART devices (the signals are electrically compatible). Apair of modules combines to provide redundancy at the fieldbus module (FBM) level, with field inputs wired to one common termination assembly (see Figure 1, page 4). In this configuration, one FBM216b is the Master, and the other is the Tracker.

FEATURES

 • 8individually isolated analog input channels. Each channel accepts one of the following inputs: 

 ◦ Standard 4 to 20 mAanalog sensor signal 

 ◦ Digital HART Frequency Shift Keying (FSK) signal superimposed on a 4 to 20 mAanalog signal 

 • Modulepair offers redundancy at the FBM level 

 • FSKmodemdedicatedtoeachinput channel for bi-directional digital communications with a HART field device 

 • Analogto digital conversion of each of the 4 to 20 mA input signal from the HART devices 

 • Support for the HARTuniversal commands necessary to interface the field device with the Foxboro DCS database 

 • Perchannel galvanic isolation of each of the eight input channels from each other, ground and module logic 

 • Ruggeddesignsuitable for enclosure in Class G3 (harsh) environments per ISA Standard S71.04 

 • Highaccuracy achieved by sigma-delta conversions for each channel 

 • Termination Assembly (TA) for locally or remotely connecting field wiring to the FBM216b 

 • TAprovide for per channel internally and/or externally loop powered transmitters

Product Overview

The FBM216 P0917TN module is a redundant HART® communication input module from FOXBORO that provides eight independently isolated input channels, each of which can receive either a HART® digital signal or a standard 4 to 20 mA analogue signal from field devices. The module supports bi-directional digital communication from HART® devices and is capable of converting received analogue signals into digital signals for communication with Foxboro DCS (Distributed Control System).

Technical Features

Redundant design:

The FBM216 P0917TN module features a redundant design where a pair of modules can be combined to provide redundancy at the fieldbus module (FBM) level. This design improves the reliability and stability of the system. Even if one module fails, the other module can still work normally, ensuring continuous operation of the system.

Eight channels of isolated inputs:

The module provides eight independently isolated input channels, each of which can receive signals from field devices. This design not only improves the anti-interference ability of the signals, but also allows the module to adapt to different field environments and equipment types.

HART® communication function:

The FBM216 P0917TN module supports the HART® communication protocol, which allows bidirectional digital communication with field devices that comply with the HART® specification. This enables the module to receive status information, diagnostic information, configuration information, etc. from field devices, enabling remote monitoring and management of field devices.

High-precision analogue-to-digital conversion:

The module has a built-in high-precision analogue-to-digital converter that converts the received analogue signals into digital signals. This conversion not only improves signal accuracy and stability, but also enables the module to communicate and control Foxboro DCS more accurately.

Easy to install and maintain:

The FBM216 P0917TN module has a compact design that allows it to be easily mounted on the baseboard of a Foxboro DCS. The front of the module also provides intuitive status indicators and fault alarms for easy troubleshooting and maintenance.

Application Areas

FBM216 P0917TN redundant HART® communication input module is widely used in industrial automation control systems, especially in the occasions where high accuracy, high reliability and redundant design are required. It is suitable for many industries such as petroleum, chemical, electric power, metallurgy, etc. It provides stable and reliable communication and control interfaces for various field devices.
