Description

Product Overview

The Foxboro FBM201 P0916AA is a high-performance,8-channel analog input module designed for use within the Foxboro I/A Series®distributed control system(DCS),a leading platform in industrial process automation.As part of the Fieldbus Interface Module(FBM)family,the FBM201 P0916AA provides precise and reliable acquisition of analog process signals—specifically 4-20mA current loops—from field instrumentation such as pressure transmitters,temperature sensors,flow meters,and level gauges.Engineered for mission-critical applications,this module delivers 16-bit resolution and galvanic isolation on all channels,ensuring signal integrity and protection against ground loops,electrical noise,and transient surges common in harsh industrial environments.

Integrated directly into the I/A Series RNI(Redundant Network Interface)or non-redundant chassis,the Foxboro FBM201 P0916AA operates as a key component in real-time process monitoring and control strategies.Each of its eight input channels is individually configurable and supports HART communication when used with compatible smart field devices,enabling access to diagnostic data,calibration parameters,and device status without interrupting the 4-20mA signal.The module communicates seamlessly with the system’s controllers and operator workstations via the I/A Series Universal Network(IUN),ensuring fast,deterministic data transfer for closed-loop control,alarming,and historical trending.With its robust design,high accuracy(±0.1%typical),and support for both redundant and standalone configurations,the Foxboro FBM201 P0916AA is a trusted solution for maintaining process stability,safety,and efficiency in industries such as oil&gas,chemical processing,power generation,and water treatment.

Main Features and Advantages

The Foxboro FBM201 P0916AA excels in reliability,precision,and integration within complex control architectures.Its 8-channel 4-20mA input capability allows for high-density signal acquisition,reducing the number of modules and rack space required in large-scale systems—ideal for retrofitting legacy plants or optimizing new installations.The 16-bit resolution ensures fine granularity in process measurement,enabling tighter control and improved product quality,especially in applications requiring sensitive regulation such as reactor temperature or distillation column pressure.

A standout feature is the galvanic isolation on all channels,which prevents ground loops and protects both the control system and field devices from voltage spikes and electrical interference—common in environments with high-power motors,variable frequency drives(VFDs),or lightning-prone areas.The HART communication support adds significant value by enabling remote diagnostics,calibration verification,and asset management without the need for physical access to the field transmitter,reducing maintenance costs and downtime.

The FBM201 P0916AA also supports redundant configurations when paired with a redundant FBC(Fieldbus Communications)processor and dual RNI networks,ensuring continuous operation even during module or network failures.Built-in LED indicators provide real-time visual feedback on module health,communication status,and individual channel faults,simplifying troubleshooting and commissioning.With its seamless integration into the I/A Series Workstation software suite,the module can be easily configured,monitored,and scaled across thousands of I/O points.Its long-standing reputation for durability and performance has made the Foxboro FBM201 P0916AA a cornerstone of industrial automation systems worldwide.

Application Field

The Foxboro FBM201 P0916AA is widely deployed in process industries where accurate and reliable analog signal acquisition is essential.In oil refineries,it monitors critical parameters such as crude oil pressure,distillation tower temperature,and fuel gas flow,feeding data into safety and control systems to prevent overpressure or overheating.Chemical plants rely on the module to maintain precise control over reaction conditions,ensuring product consistency and regulatory compliance.

In power generation facilities,the Foxboro FBM201 P0916AA is used to monitor boiler feedwater levels,steam pressure,and turbine bearing temperatures—key inputs for protective interlocks and automatic control loops.Water and wastewater treatment plants use it to track flow rates,tank levels,and chemical dosing levels,enabling efficient resource management and environmental compliance.
