ABB 086370-001

Description

Product Description

The ABB 086370-001 is a specialized power supply and signal conditioning module that serves as an essential interface for the CI871 PROFIBUS communication module within the AC 800M controller family. This module is not a standalone communication processor but a critical partner unit that provides the necessary power conversion, electrical isolation, and physical connection interface for the main CI871 module to function. It acts as the bridge, allowing the CI871 to be mounted in the AC 800M rack while safely and reliably connecting to the external PROFIBUS DP network. Without the 086370-001, the CI871 module cannot operate, as it relies on this interface for power from the controller’s backplane and for a protected connection to the fieldbus. The design of the ABB 086370-001 ensures that sensitive controller electronics are shielded from the electrical noise and potential ground loops prevalent in industrial fieldbus environments, making it a vital component for robust system integration.

Product Parameters

• Module Type: Interface/Power Supply Module for Communication Unit

• Compatible Main Unit: Designed exclusively for use with the ABB CI871 PROFIBUS DP Master/Slave communication module.

• Primary Function: Provides power conversion and galvanic isolation for the CI871 module.

• Input Power: Supplied from the AC 800M baseplate.

• Isolation: Provides high-grade galvanic isolation between the AC 800M controller internal circuitry and the PROFIBUS network.

• Physical Interface: Contains the terminal connectors or sub-D port for the PROFIBUS network cable connection.

• Mounting: Attaches directly to the CI871 module, forming a single combined unit for installation in an AC 800M I/O slot.

• Status Indicators: Operational status is typically relayed through LEDs on the main CI871 module.

• Operating Temperature: 0°C to +60°C (standard for AC 800M periphery).

Advantages and Features

• Guaranteed System Integrity: The ABB 086370-001 is engineered to provide clean, regulated power and robust isolation, which are prerequisites for the stable and error-free operation of the CI871 PROFIBUS master.

• Critical Network Protection: It protects the valuable AC 800M controller from electrical transients, noise, and ground potential differences that can be carried on the PROFIBUS cable, thereby preventing damage and communication faults.

• Optimized Modular Design: This two-part design (CI871 + 086370-001) separates the complex communication processor from the power and interface electronics. This enhances reliability, simplifies troubleshooting, and allows for more cost-effective repairs by replacing only the faulty unit.

• Seamless Integration: Using the official ABB 086370-001 ensures perfect mechanical fit, electrical compatibility, and full support within the Control Builder M engineering environment for the entire CI871 configuration.

• Service-Friendly: The modular nature allows technicians to quickly swap the interface module or the communication processor independently, minimizing system downtime during maintenance.

Application Cases in Various Fields

• Process Automation (Chemical, Pharmaceutical): Enables an AC 800M controller to act as a PROFIBUS DP master, connecting to remote I/O stations and variable speed drives across a plant, with the 086370-001 ensuring reliable communication in electrically noisy areas.

• Manufacturing & Automotive: Used in a production cell where an AC 800M coordinates multiple robots and conveyors via PROFIBUS. The interface module is key to maintaining deterministic data exchange.

• Energy Management: Facilitates the integration of an AC 800M-based substation controller into a larger plant-wide PROFIBUS network for data aggregation and supervisory control.

• Water Treatment: Allows a central AC 800M controller to communicate with intelligent motor starters and valve actuators distributed throughout a treatment facility via a PROFIBUS DP network.

Comparisons with Competing Products

The ABB 086370-001 does not have a direct competitor in the traditional sense, as it is a proprietary interface for a specific ABB system component. Meaningful comparisons include:

1. System Architecture Differences: Compared to other PLC platforms (e.g., Siemens S7-400), where PROFIBUS master functionality is often integrated on the CPU or a separate card with built-in interfaces, the ABB AC 800M approach using the CI871 paired with the 086370-001 represents a highly modular and service-optimized design philosophy.

2. Using an Incomplete System: Attempting to operate a CI871 module without the 086370-001 is impossible, as it lacks power and a physical network port. This underscores its role as a non-optional, critical system component.

3. Generic Solutions: Third-party PROFIBUS couplers or isolators cannot replace the 086370-001, as they are not designed to mate mechanically and electrically with the CI871’s form factor and internal communication protocol.

Selection Suggestions and Precautions

1. Mandatory Purchase as a Set: The ABB 086370-001 must always be purchased and used in conjunction with its corresponding CI871 communication module. They are functionally one unit split across two physical pieces.

2. Verify Exact Revision Compatibility: Ensure that the revision of the 086370-001 interface module is compatible with the revision of your CI871 module by checking ABB’s hardware documentation or product notes. Mismatches can cause malfunctions.

3. Handle with ESD Precautions: Both the CI871 and the 086370-001 contain static-sensitive electronics. Use proper ESD straps and handling procedures during installation or replacement.

4. Power Down for Maintenance: Always power down the AC 800M controller before installing, removing, or swapping the 086370-001 and its attached CI871 module to prevent hardware damage.

5. Spare Part Strategy: For critical processes, it is prudent to keep a spare ABB 086370-001 and CI871 module set on hand. This allows for rapid replacement and restoration of PROFIBUS communication in the event of a failure, with the old units sent for repair.
