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

Remote reading of diagnostic information, range settings, and calibration data from smart devices such as HART transmitters;

Remote configuration and calibration of on-site HART devices through the main controller, without the need for on-site operation.

HART data processing: Supports HART universal instructions, conventional operation instructions, and device specific instructions. The main controller can receive multiple digital messages from each HART device per second, meeting real-time monitoring and control requirements.

（3） Installation and maintenance convenience

Modular design:

The remote I/O module and terminal components adopt a modular structure and support "hot plugging" (some models). When replacing the module, there is no need to disconnect the on-site wiring or interrupt the system operation, reducing maintenance downtime.

The module size is compact (such as height ≤ 150mm, width ≤ 30mm), and can be installed on DIN rails or small cabinets, suitable for on-site environments with limited space.

Simplified wiring:

Remote deployment reduces the long-distance wiring of on-site equipment to the central cabinet, lowering cable costs and construction difficulties;

The terminal component supports the "one in, multiple out" wiring method, which can simultaneously connect multiple on-site devices of the same type, simplifying the wiring logic.

Configuration tool support:

Compatible with Foxboro I/A Series system configuration software (such as FoxDraw, Control Builder), remote I/O module channel parameters (such as range, alarm threshold, fault safety action) can be configured remotely through the software without on-site debugging.

（4） Environmental adaptability

Protection level: When the remote I/O unit is paired with a dedicated protective casing, the protection level can reach IP65/IP67, and it can be directly installed outdoors or in dusty, humid, and corrosive environments (such as chemical workshops and refinery sites).

Temperature and humidity range:

Working temperature: -20 ° C to+60 ° C (some models support a wide temperature range of -40 ° C to+70 ° C);

Working humidity: 5% -95% (non condensing), suitable for high humidity industrial environments;

Anti vibration performance: Within the frequency range of 5-500Hz, it operates stably under a vibration intensity of 7.5m/S ² (0.75g), meeting the requirements of industrial site vibration environment.
