DeltaV ™ Flex Connect Solutions for Foxboro ™ I/A Series 100 I/O

Application scenarios and supporting documents

（1） Typical application scenarios

The FlexConnect solution is mainly suitable for industrial process automation scenarios of Foxboro I/A Series 100 I/O systems, especially for the following needs:

In scenarios where on-site equipment is dispersed, such as large chemical parks and refineries, where equipment is distributed over a wide area, remote I/O deployment can reduce long-distance wiring costs;

Adverse environmental scenarios: such as outdoor storage tank areas, high temperature/high humidity workshops, modules with IP65/IP67 protective enclosures can be directly installed without the need for additional protective cabinets;

High reliability requirements scenarios: such as power systems, oil platforms, redundant communication and power supply design to ensure uninterrupted process control;

Intelligent device intensive scenarios: such as process industries equipped with a large number of HART transmitters, the solution can efficiently integrate HART digital communication to achieve remote management of intelligent devices.

Core differences from traditional I/O solutions

Comparison Dimension FlexConnect Solution Traditional Foxboro I/A Series 100 I/O Solution

Deployment method: remote/distributed deployment, centralized deployment near on-site equipment, all cables need to be pulled to the central cabinet

Reduce wiring costs by more than 50%, reduce cable and construction costs for long-distance wiring, which is costly and complex to construct

The maintenance efficiency module supports hot plugging, local LED alarms, and quick fault location. It requires opening the central cabinet for maintenance, and fault diagnosis relies on controller data

Environmental adaptability supports IP65/IP67 protection and is suitable for harsh/outdoor environments. It relies on central cabinet protection and cannot be directly exposed to harsh environments

Redundancy capability: Communication and power dual redundancy, with millisecond level fault switching. Only some core modules support redundancy, and communication redundancy requires additional configuration
