Description

Foxboro  FBM215  HART Communication Output Module

• Channel Configuration: Equipped with 8 output channels. Each channel can provide a 4-20mA analog output signal and also output a digital HART Frequency Shift Keying (FSK) signal superimposed on the analog signal, supporting any combination of standard 4-20mA devices and HART devices.
• Communication Function: Each output channel is equipped with an FSK modem for bidirectional digital communication with HART field devices. It can act as a HART communication field device host, enabling the Foxboro Evo system to request and receive two digital messages from each field device per second. It supports message pass-through functions for HART universal commands, common commands, and specific device commands, but does not support burst communication mode.
• Electrical Isolation: All output channels are electrically isolated from each other, from ground, and from module logic, which improves the anti-interference ability and operational stability of the module.
• Structural Design: Adopts a compact design with a sturdy Acrylonitrile Butadiene Styrene (ABS) shell, which can provide good physical protection for internal circuits and adapt to harsh industrial environments such as G3 level. The front of the module is equipped with Light-Emitting Diodes (LEDs) to visually display the module’s operating status and channel communication activities.
• Installation Method: Installed on the Compact 200 series backplane, which can be mounted on a DIN rail or horizontally on a rack using a kit. When removing or replacing the module, there is no need to remove the on-site equipment terminal cables, power supply, or communication cables, making maintenance convenient.
• Power Supply: Provides isolated power for each channel to ensure the power supply stability and independence of each channel.

• Input and Output Parameters:
  • Number of Output Channels: 8.
  • Output Signal Type: 4-20mA analog signal, or digital HART FSK signal superimposed on 4-20mA analog output.
• Electrical Parameters: Usually powered by 24VDC, and specific parameters such as power consumption may vary according to actual application scenarios.
• Mechanical Parameters: Compact in size, and the specific dimensions may vary slightly depending on the product version and other factors. The shell is made of ABS, which has certain strength and durability.
• Environmental Parameters: Can adapt to a wide operating temperature range, generally working normally in the environment of -40°C to +70°C, and the protection level can also meet the requirements of general industrial sites.

• Oil and Gas Industry: In this industry, a large number of on-site equipment need to be precisely controlled. The FBM215 module can transmit the instructions of the control system to equipment such as flow control valves and pressure control valves at the wellhead through the HART protocol, realizing precise regulation of wellhead flow and pressure. At the same time, it can also receive the status information fed back by these equipment, facilitating operators to grasp the equipment operation in real-time and ensuring the stability of the extraction and transportation process.
• Chemical Industry: The chemical production process is complex, and the control requirements for process parameters are extremely high. FBM215 can be used to control the feed valve, discharge valve, and temperature regulation device of the reactor. Through HART communication, the valve opening and the amplitude of temperature regulation are precisely controlled according to process requirements to ensure the stability of reaction conditions, thereby improving product quality and output. It can also communicate with on-site analytical instruments, such as pH meters and concentration meters, to transmit measurement data to the control system for timely adjustment of production processes.

• Power Industry: In the thermal system of a power plant, FBM215 can control equipment such as the speed control valve of the steam turbine and the feed water control valve of the boiler, and precisely adjust the valve opening according to the operating status of the unit to ensure the stable operation of the unit. In the water treatment system, it can also be used to control the flow of the dosing pump, and the dosage can be adjusted in real-time through the HART protocol according to the water quality test results to ensure that the water quality meets the requirements.
• Metallurgical Industry: In the metallurgical production process, FBM215 can be used to control equipment such as the distribution valve and hot blast valve of the blast furnace, as well as the oxygen lance lifting and oxygen blowing valve of the converter. Through precise control of these equipment, the smelting process can be optimized, and the quality of molten iron and molten steel can be improved. At the same time, it can also communicate with on-site temperature and pressure sensors, etc., to transmit data to the control system, providing a basis for the monitoring and adjustment of the production process.
• Sewage Treatment Industry: In sewage treatment plants, FBM215 can control the aeration valve of the aeration tank. According to the dissolved oxygen content in the tank, the valve opening is automatically adjusted through the HART protocol to achieve precise aeration and reduce energy consumption. It can also control the sludge discharge valve of the sludge thickening tank, and reasonably control the sludge discharge amount according to parameters such as sludge concentration and liquid level to ensure the normal operation of the sewage treatment process.
