Description
FOXBORO FBM216b is a high-performance processor module,commonly used in industrial automation and control systems.The following is a detailed introduction to FOXBORO FBM216b:
I.Main features
Redundant HART communication input:FBM216b has redundant HART communication input function,which means it can process signals from multiple HART field devices at the same time,improving the reliability and stability of the system.
Multiple independent isolated input channels:The module contains 8 independent isolated analog input channels,each of which can accept standard 4 to 20mA analog sensor signals,or digital HART frequency shift keying(FSK)signals superimposed on 4 to 20mA analog signals.
High-precision analog-to-digital conversion:FBM216b can convert each 4 to 20mA input signal from a HART device into analog-to-digital to achieve high-precision signal processing and transmission.
Support for HART universal commands:The module supports the HART universal commands required for field devices to interface with the Foxboro DCS database,which is convenient for users to configure,monitor and diagnose equipment.
Electrical isolation design:Each of the eight input channels is electrically isolated from each other,from the ground,and from the module logic,improving the safety and stability of the system.
Rugged housing design:The FBM216b has a rugged housing design suitable for G3(harsh)environments,ensuring the normal operation of the module under various harsh conditions.
II.Functions and applications
Functions:The FBM216b can be used as a HART communication field device host,enabling the Foxboro DCS to request and receive two digital messages per second from field devices.In addition,it also supports message pass-through function,which can be used to support HART general,common and specific device commands.
Application areas:The FBM216b is widely used in industrial automation,control systems,data acquisition and monitoring.In the power industry,oil and gas extraction,manufacturing,water treatment and sewage treatment,and building automation industries,the module plays an important role.
III.Technical specifications
Interface:8 independent isolated channels,the communication mode with the device is point-to-point,master/slave,asynchronous,half-duplex,1200 baud.
Speed:2 messages can be processed per second.
Maximum Distance:The maximum distance from the FBM216b to the field device is 3030 meters(10,000 feet),in compliance with the HART FSK physical layer specification.
Power:Each channel achieves high accuracy throughΣ-Δconversion,and a separate isolated power supply is provided to power the eight channels.In addition,a terminal assembly(TA)is provided for connecting the field wiring to the FBM216b locally or remotely.
Accuracy and Resolution:Analog accuracy(including nonlinearity)is±0.075%of full scale,with a resolution of 15 bits.
