Information

Overview Manuals Common Applications Product Precautions

490NRP25400 bridges a defined Modbus Plus segment across its approved copper and optical media, so topology, port direction and network continuity remain a single engineered route.

Operates as a Modbus Plus line/drop repeater and transceiver.
Links documented copper and optical-fiber network media.
Extends a controlled network path without changing the node map.
Has no direct replacement identified in the Schneider Electric FAQ.

Modbus plus line/drop signal conversion and optical-fiber extension depends on the exact installed host, wiring, configuration and controlled acceptance record.

Important Notice: Match 490NRP25400 to the complete installed record and verify every affected function before service release.

Modbus Plus fiber extension

Carries a documented network segment across optical fiber.

Copper-to-fiber transition

Maintains communication between approved copper and optical media.

Electrical isolation planning

Supports a controlled fiber segment where the architecture requires media separation.

Legacy network maintenance

Preserves node order and repeater direction while renewing a field device.

Read the applicable product and site instructions before work. Verify 490NRP25400, the installed host and every connected interface before isolation or replacement.

Confirm 490NRP25400 and the complete Modbus Plus segment drawing before work.

Place all affected network nodes in the approved maintenance state.

Record copper ports, fiber transmit/receive direction and node order before removal.

Protect optical connectors from dust, moisture and end-face damage.

Maintain documented cable routing, bend radius and mechanical strain relief.

Restore transmit-to-receive pairing and every shield or grounding provision.

Review communication counters and node status after controlled energization.

Test the complete segment in both directions before releasing 490NRP25400.

Technical notes

Match 490NRP25400 to the exact Modicon Quantum / Modbus Plus position and preserve every documented connection, setting and companion component. After replacement, review diagnostics and verify Modbus Plus line/drop signal conversion and optical-fiber extension under controlled conditions.
