ABB AIM0006 2RCA021397A0001F

Description

Product Overview

The ABB AIM0006 2RCA021397A0001F is a highly specialized Intrinsically Safe (IS) Analog Input Module designed for the ABB 800xA Extended Automation System, specifically within its High Integrity/Safety Instrumented System (SIS) portfolio. This module serves as a critical interface for connecting analog field signals from sensors located in hazardous areas (e.g., Zones 0, 1, 2 for gas/dust) to the safety controller. The ABB AIM0006 ensures that the signals are safely transmitted by providing the necessary energy limitation as per ATEX/IECEx standards, preventing any potential ignition source from reaching the hazardous area.

Key Product Parameters

• Product Type: Intrinsically Safe (IS) Analog Input Module for Safety Systems

• Compatible System: ABB AC 800M HI (High Integrity) Safety Controller within the 800xA system.

• Part Numbers: AIM0006 (functional type), 2RCA021397A0001F (specific orderable article number/code).

• Safety Certification: Certified for use in Safety Instrumented Systems (SIS), supporting SIL 2/SIL 3 applications as per IEC 61508/61511.

• Intrinsic Safety: Provides galvanic isolation and energy limitation for connection to IS field devices. Certified for specific entity parameters (Ui, Ii, Pi, Ci, Li).

• Channels: Typically features a defined number of analog input channels (e.g., 4 or 8), each with individual IS barriers.

• Input Signal: Accepts standard IS 4-20 mA signals from transmitters in hazardous areas.

• Diagnostics: Extensive channel-level diagnostics including wire-break, short-circuit, and out-of-range detection, which are crucial for safety loop availability.

• Connection: Uses certified IS terminals and may interface via an IS fieldbus or directly to the safety controller’s I/O bus.

Advantages and Core Features

The paramount advantage of the ABB AIM0006 2RCA021397A0001F is its combination of functional safety integrity and intrinsic safety in a single, integrated module. This dual certification simplifies system design for hazardous area applications by eliminating the need for separate safety barriers or isolators. Its seamless integration with the AC 800M HI controller allows for unified configuration and diagnostics within the 800xA engineering environment. The module’s high diagnostic coverage enables predictive maintenance and ensures the health of the safety loop is constantly monitored, a critical requirement for maintaining the required Safety Integrity Level (SIL). The robust design of the AIM0006 is tailored for maximum reliability in critical processes.

Application Scenarios

This module is deployed in process industries where safety-critical measurements must be taken from explosive atmospheres:

• Oil & Gas (Upstream & Refining): Connecting pressure, temperature, and level transmitters from hazardous zones on offshore platforms, in refineries, or on LNG trains to the Safety Instrumented System (SIS).

• Chemical & Petrochemical Plants: Interfacing with analog sensors in reactor areas, storage tank farms, and ethylene cracker units for emergency shutdown (ESD) functions.

• Pharmaceuticals: Where solvent handling creates hazardous areas, connecting sensors for fire & gas detection or process interlocks.

• Paint & Coating Manufacturing: Monitoring conditions in spray booths and solvent mixing areas.

Comparison with Competing Products

Competing products include IS analog input modules from other safety system vendors like Honeywell (Safety Manager IS I/O), Emerson (DeltaV SIS with IS CHARMs), and Siemens (Simatic PCS 7 S7-400 F/FH with IS interface modules). The ABB AIM0006 is distinguished by its native integration within the 800xA High Integrity architecture, offering a single engineering toolset for both control and safety in hazardous areas. Compared to using a standard analog input card with external safety barriers, the integrated AIM0006 solution offers superior diagnostics, reduced wiring, simpler certification documentation, and a more compact footprint.

Selection Guide and Important Notes

Selecting the ABB AIM0006 2RCA021397A0001F is a specialized task integral to designing a SIL-rated safety loop for a hazardous area. It requires careful safety engineering.

Important Precautions:

• Certified System Integration: This module must be used as part of a certified ABB High Integrity safety loop. All components (controller, power supply, field device) must be compatible and the loop design must be validated.

• Entity Parameter Matching: The IS parameters (Ui, Ii, Pi, Ci, Li) of the AIM0006 channel must be matched with the entity parameters of the field device and the intervening cable to ensure intrinsic safety is maintained. This calculation is mandatory.

• Installation & Wiring: Installation must strictly follow ABB’s instructions, national electrical codes (e.g., NEC, IEC), and hazardous area installation standards (e.g., for explosion-proof conduits, cable glands, and separation). Only trained and certified personnel should perform this work.

• Documentation: Full loop documentation, including the Safety Requirements Specification (SRS), loop drawings, and entity parameter calculations, must be maintained for audit and recertification purposes.

• Proof Testing: The entire safety loop, including the AIM0006 module, will have a mandated proof test interval that must be adhered to as part of the Safety Lifecycle management.
