BARTEC 07-7311-97WP5400 S900 PROFIBUS Ring Coupler

Description

Specifications

The BARTEC 07-7311-97WP5400 is documented by ABB’s S900 Remote I/O documentation as the BARTEC component used with both the BI923S and BI924S ring-coupler configurations. BI923S is the slave version, while BI924S is the master version. Both separate an intrinsically safe fiber-optic ring from a non-intrinsically-safe RS485 fieldbus interface and use an FSMA optical connection in a DIN-rail housing with IP20 protection.

The corresponding ABB article numbers are 3KDE175831L9230 for BI923S and 3KDE175831L9240 for BI924S. This distinction matters when sourcing a replacement because the BARTEC part number alone does not tell you whether the installed S900 configuration is being used as a master or slave.

Product Introduction

The BARTEC 07-7311-97WP5400 is an intrinsically safe communications component associated with the ABB S900 Remote I/O system. It provides the physical interface between a fiber-optic ring and an RS485 fieldbus connection, allowing the S900 architecture to use fiber-based communication where intrinsic-safety requirements apply.

The part number is used in two closely related configurations: BI923S, which operates as a slave ring coupler, and BI924S, which operates as a master ring coupler. Therefore, replacement procurement should verify the complete ABB article number and the role of the existing module rather than matching only the BARTEC number.

Installation Guide

Stage 1 — Pre-Installation

1. Apply the plant’s approved LOTO procedure and isolate the associated equipment.
2. Confirm the hazardous-area/intrinsic-safety requirements before disconnecting the fieldbus.
3. Record the existing ABB article number: 3KDE175831L9230 or 3KDE175831L9240.
4. Determine whether the installed unit is functioning as or .
5. Photograph the RS485 wiring, fiber connections, module position, and termination arrangement.
6. Record the fiber connector type and cable routing before removal.
7. Verify that the replacement BARTEC unit carries the complete 07-7311-97WP5400 designation.

Stage 2 — Remove the Existing Module

1. Verify that the system is in the approved maintenance state.
2. Disconnect the RS485 fieldbus connection according to the plant procedure.
3. Protect the FSMA fiber connector from dust and mechanical damage.
4. Do not bend or sharply kink the fiber cable during removal.
5. Release the DIN-rail-mounted module from the termination arrangement.
6. Inspect the terminals and fiber connector for contamination, corrosion, or physical damage.
7. Check the surrounding termination hardware before installing the replacement.

Stage 3 — Install the 07-7311-97WP5400

1. Verify whether the replacement is required for the or configuration.
2. Install the unit in the original DIN-rail position.
3. Reconnect the fieldbus using the documented terminal arrangement.
4. Clean and inspect the FSMA optical connection before mating the fiber connector.
5. Reconnect the fiber ring without exceeding the cable manufacturer’s bend-radius specification.
6. Verify that the replacement occupies the same system position as the original.
7. Confirm the required fieldbus termination and network topology before power-up.

Stage 4 — Power-Up and Functional Test

1. Complete a wiring and connector inspection before energizing the system.
2. Restore power according to the plant commissioning procedure.
3. Check the ring-coupler diagnostic indicators, if provided.
4. Verify communication between the equipment and the connected fieldbus.
5. Verify the fiber-optic ring connection and communication path.
6. Confirm that the correct master/slave relationship is established.
7. Check the controller for communication diagnostics or station faults.
8. Verify representative field I/O before returning the process to normal operation.

Technical pitfall: The most important replacement check is versus . Both configurations use BARTEC 07-7311-97WP5400, but is documented as the slave ring coupler and as the master ring coupler. Using the wrong system role can prevent the communication architecture from operating correctly.

For surplus or refurbished inventory, supplier QC should include visual inspection, FSMA connector inspection, continuity checks, fiber-link testing, master/slave communication verification, network testing, and final part-number/revision verification. These tests should only be described as completed when an actual test record is available.

FAQ

1. What is BARTEC 07-7311-97WP5400?

It is a BARTEC /fiber-optic ring-coupler component used in ABB Remote I/O systems for intrinsically safe fieldbus communication.

2. Which ABB modules use 07-7311-97WP5400?

The part number is documented for both and . is the slave configuration, while is the master configuration.

3. What are the ABB article numbers?

The documented ABB article number for is 3KDE175831L9230, while the master version is 3KDE175831L9240.

4. What type of fiber connector does it use?

The documentation specifies an FSMA optical plug for the and configurations.

5. Is 07-7311-97WP5400 itself the complete or module?

The documentation associates the BARTEC number with both ring-coupler variants. For procurement, verify the complete ABB article number and master/slave role rather than assuming that the BARTEC number alone identifies the required system configuration.

6. Can a standard repeater replace this component?

Not as a direct substitution. The 07-7311-97WP5400 is used within an intrinsically safe fiber-ring architecture, so the replacement must satisfy the applicable intrinsic-safety and communication requirements.

7. What should I verify before buying a used or surplus unit?

Confirm BARTEC 07-7311-97WP5400, the corresponding ABB article number, / role, FSMA fiber interface, connection, physical condition, and actual communication-test results. For hazardous-area applications, also verify the applicable intrinsic-safety certification and installation requirements before commissioning.
