Foxboro Products and Solutions

Foxboro hardware at PLC Direct covers DCS control processors, I/O modules, field transmitters, standalone process controllers, safety system modules, and network infrastructure used across installed Foxboro process control and instrumentation systems.

Foxboro Product Families

I/A Series Distributed Control System: The I/A Series is Foxboro’s flagship distributed control system platform, widely deployed in process manufacturing facilities for regulatory, logic, and sequential process control. The DCS architecture centers on zone control processors and field control processors that communicate with Fieldbus Modules (FBMs), which handle analog and digital I/O at the field level. Confirmed hardware in the PLC Direct collection includes the ZCP270 Zone Control Processor, a distributed, optionally fault-tolerant controller that connects to the MESH control network via 100 Mbps fiber optic Ethernet and supports up to 128 of the 200 Series FBMs, and an extensive range of FBM I/O modules. Confirmed FBM part numbers include FBM217-P0914TR, FBM207TA, and FBM212-P0914XL, covering analog and discrete I/O functions for field device interfacing. The P081 series part numbers in the collection are confirmed I/A Series hardware.
I/A Series Field Transmitters: Foxboro’s I/A Series field transmitter family covers differential pressure, gauge pressure, absolute pressure, flow, temperature, and level measurement for process instrumentation applications. Key transmitter series include the IDP10 and IDP50 differential pressure transmitters, the IGP10 and IGP20 gauge pressure transmitters, the IAP10 and IAP20 absolute pressure transmitters, and the IMV25 and IMV30 multivariable transmitters. All I/A Series transmitters support HART, FoxCom, and FOUNDATION Fieldbus communication protocols and are available with 4-20 mA analog output. They feature NEMA 4X and IP66-rated aluminum or 316 stainless steel housings and are certified for hazardous-area installation under ATEX, IECEx, FM, and CSA standards.
762 Series Single Station Micro Controllers: The Foxboro 762 series is a standalone single- and dual-loop process controller that provides PID control, EXACT adaptive tuning, and algebraic calculation capability in a self-contained unit. The 762CNA Single Station Micro Controller supports two independent control loops, RS-485 serial communication, and direct process measurement input, making it suitable for standalone loop control applications where a full DCS is not required. Confirmed in the PLC Direct collection is the 762MMHO variant.
SCD6000 Safety and Critical Control System: The Foxboro SCD6000 is a SIL 3-rated safety instrumented system using Triple Modular Redundant (TMR) architecture for emergency shutdown (ESD), fire and gas detection, and critical process control applications. SCD6000 hardware is certified to IEC 61508 and IEC 61511 and is used in oil and gas, refining, and petrochemical facilities where an independent safety system is required to protect personnel, equipment, and the environment. Confirmed SY-prefix SCD6000 modules in the PLC Direct collection include SY0303460RA, SY-610250004R, and SY-61025001RA.
I/A Series Network Infrastructure: Industrial Ethernet switching hardware configured for Foxboro I/A Series DCS network architectures. The collection includes the X440-G2-24FX-GE4, an Extreme Networks X440 industrial managed Ethernet switch with fiber and copper ports, configured for the high-availability Foxboro MESH control network.

Frequently Asked Questions

We carry Foxboro I/A Series DCS hardware, including ZCP270 zone control processors, FBM series Fieldbus Modules, and I/A Series network switches; I/A Series field transmitters for pressure, flow, temperature, and level measurement; 762 Series standalone process controllers; and SCD6000 TMR safety system modules. Contact us with your part number to check current availability and condition grade.

The I/A Series is Foxboro’s distributed control system platform for process manufacturing. The architecture centers on zone or field-control processors that execute control strategies and communicate with Fieldbus Modules (FBMs) that handle field-level I/O. FBMs connect to field instruments and actuators, converting field signals to and from the DCS network. The ZCP270 is a zone control processor that manages multiple FBMs and connects to the MESH control network via 100 Mbps fiber optic Ethernet, supporting regulatory, logic, timing, and sequential control for large-scale process applications.

The SCD6000 is Foxboro's safety instrumented system platform, rated to SIL 3 per IEC 61508 and IEC 61511. It uses Triple Modular Redundant architecture, three independent processing channels that vote on outputs, to ensure the system continues to function correctly even when one channel develops a fault. SCD6000 systems are used for emergency shutdown, fire and gas detection, and critical process control in oil and gas, refining, and petrochemical facilities where the safety function must operate independently of the basic process control system.

Foxboro I/A Series pressure, differential pressure, and multivariable transmitters are installed across oil and gas, refining, petrochemical, chemical, pharmaceutical, power generation, pulp and paper, and water treatment facilities. They are used wherever precise measurement of process pressure, flow (via differential pressure), level, or temperature is required for control loop input or process monitoring.
