EMERSON EP206-I00-EN00 l/O interface module

Product Detailed Description:

The Emerson EP206-I00-EN00 is a Fieldbus Link Device, specifically designed to facilitate communication and connectivity within Foundation™ Fieldbus H1 networks. It acts as an H1 Link Device, providing essential functions to manage and enhance the performance of the Fieldbus segment. This device enables the connection of multiple Fieldbus devices, allows for the creation of device groups, manages communication resources, and helps ensure deterministic operation on the network. It essentially acts as a communication “traffic controller” and resource manager for the Fieldbus segment it is connected to, optimizing data exchange between field devices and the control system.

Product Parameters:

(Note: Specific parameter values can vary slightly based on firmware versions and configuration. These are typical examples)

• Protocol: Foundation™ Fieldbus H1

• Communication Rate: 31.25 kbps

• Segment Power: Typically supports up to 32 devices per segment (subject to power budget and device requirements).

• Communication Resources: Provides resources like Communication Resource Function (CRF) and Link Active Scheduler (LAS) capabilities, which can be allocated to devices on the segment.

• Number of H1 Terminals: Typically 2 H1 terminals for segment connection.

• Power Consumption: Low power consumption, typically around 0.5 W.

• Operating Temperature: Typically -40°C to +85°C (check specific datasheet).

• Relative Humidity: Typically 5% to 95% non-condensing.

• Certifications: Usually includes ATEX, IECEx, CSA, and other relevant certifications for hazardous areas (check specific datasheet for details).

Product Advantages:

• Enhanced Network Performance: Improves communication reliability and determinism on the Fieldbus H1 segment by efficiently managing communication resources.

• Increased Device Density: Helps manage larger numbers of devices on a single segment by providing necessary communication resources.

• Segment Flexibility: Allows for more flexible network topologies and device groupings.

• Improved Diagnostics: Often provides enhanced diagnostic information about the segment and connected devices.

• Standardized Integration: Seamlessly integrates with Emerson’s control systems (like DeltaV™) and other Foundation™ Fieldbus compliant systems.

• Reduced Wiring: Contributes to the overall benefits of Fieldbus, including reduced cabling, installation costs, and maintenance efforts compared to traditional 4-20mA systems.

Precautions:

• Proper Installation: Ensure correct wiring according to Foundation™ Fieldbus standards. Use appropriate termination resistors at the ends of the segment.

• Power Budget Calculation: Carefully calculate the power budget for the entire Fieldbus segment to ensure all devices receive sufficient power. The EP206 itself consumes power and reduces the available budget for field devices.

• Configuration: Requires proper configuration using Fieldbus configuration tools (like DeltaV™ System or other compatible tools) to define its role (e.g., LAS provider, CRF allocation).

• Hazardous Area Compliance: If used in hazardous areas, ensure the specific model and installation comply with all relevant regulations and certifications (ATEX, IECEx, etc.). Use appropriate intrinsic safety barriers if required.

• Environmental Protection: Install the device in an appropriate enclosure that protects it from environmental factors like dust, moisture, and vibration, suitable for the installation location.

• Firmware Updates: Follow Emerson’s recommended procedures for firmware updates to maintain performance and security.

Product Applications:

• Process Industries: Widely used in oil & gas, chemical, petrochemical, refining, pharmaceutical, and water/wastewater treatment plants.

• Fieldbus Network Segmentation: Deployed to manage and optimize communication on Foundation™ Fieldbus H1 segments, especially in complex installations with many devices.

• Hazardous Area Instrumentation: Used to connect Fieldbus devices in potentially explosive atmospheres, leveraging its hazardous area certifications.

• Integration with Control Systems: Acts as an interface between field devices and Emerson’s DeltaV™ or other compatible control systems.

• Applications Requiring High Reliability: Suitable for critical process applications where reliable communication and deterministic operation are paramount.
