FOXBORO FBM204

Description

FOXBORO FBM204 is a high-performance process control module launched by Foxboro,a brand under Emerson Process Management.The following is a detailed introduction to the module:

1.Basic features

Type:High-performance process control module,integrating multiple functions such as control,monitoring,and diagnosis.

Processor:Adopts a high-performance 32-bit microprocessor,supports multi-tasking,and ensures the real-time and accuracy of the control algorithm.

Memory:Provides 2MB user memory to support program and data storage.

Communication interface:Supports multiple communication protocols such as HART,Modbus,Ethernet,etc.,which is convenient for data exchange with different devices and systems.

2.Input and output characteristics

Input channel:FBM204 has four 20mA DC analog input channels,each of which can accept analog sensor input,such as 4 to 20mA transmitter or self-powered 20mA signal source.

Output channel:It also has four 20mA DC analog output channels,each of which can drive an external load and generate 0 to 20mA output.

Electrical Isolation:The input/output is electrically isolated from other input/output channels and ground,which improves the safety and stability of the system.

III.Features

Signal Conversion:The FBM204 is able to perform signal conversion to connect the electrical input/output signals of field sensors to an optional redundant fieldbus.

Analog I/O Application:The module provides analog I/O applications with configurable options such as conversion time,fail-safe configuration(hold/fallback),and analog output fail-safe fallback data(per channel).

Distributed PIDA Application:The FBM204 can execute distributed PIDA(DPIDA)applications,providing fast control loops running in them.

IV.Technical Specifications

Accuracy:The accuracy of both input and output channels reaches±0.03%of the range,ensuring high-precision signal measurement and control.

Resolution:The output channel has a 13-bit resolution,providing higher control accuracy.

Integration Period:Software configurable to suit different application requirements.

Common Mode Rejection:At 50 or 60Hz,the common mode rejection is greater than 100dB,which improves the system’s anti-interference ability.

Output processing delay:maximum 30 milliseconds,ensuring the rapid responsiveness of the system.

5.Physical characteristics

Housing:FBM204 has a sturdy extruded aluminum housing to provide physical protection for the circuit and is suitable for cabinets in G3-level(harsh)environments.

Protection level:IP65,dustproof and waterproof,suitable for outdoor and harsh environment installation.

Operating temperature range:-40°C to 70°C(the operating temperature range mentioned in some materials is-20°C to+50°C,but-40°C to 70°C is a wider operating temperature range and may be applicable to different models or versions of FBM204),adapting to harsh industrial environments.

6.Application areas

FBM204 is suitable for industrial fields such as petrochemicals,electricity,water treatment,and pharmaceuticals,providing users with an efficient,reliable,and flexible control solution.For example,in the field of petrochemicals,it can be used in the control system of catalytic cracking units in refineries to achieve efficient and safe production;in the field of electricity,it can be used in the boiler control system of thermal power plants to improve combustion efficiency and energy utilization.
