1. Product Overview

140NRP95400C is a conformal-coated, dual‑channel multimode fiber optic repeater for Modicon Quantum RIO S908 remote I/O networks. It extends communication distance, provides electrical isolation, and supports redundant links for high availability in harsh environments.

• Coated version: Improved resistance to dust, moisture, vibration, and corrosive atmospheres.

• Form, fit, function identical to 140NRP95400 (non‑coated) except for conformal coating.

2. Key Features

• Conformal coating: For harsh industrial environments.

• Dual redundant fiber channels: 2×ST multimode ports + 1×BNC coaxial port.

• Max distance: 3,000 m (62.5/125 µm) at 1 Mbps.

• Optical isolation: Eliminates ground loops and EMI.

• Hot‑swappable: Replace without system shutdown.

• Diagnostic LEDs + relay: Real‑time status and fault alarming.

• Certifications: CE, UL 508, CSA C22.2 No.142, FM Class 1 Div 2, RoHS compliant.

4. LED Indicators & Diagnostic Relay

LED Status

表格

Diagnostic Relay

• Normal: Energized (contacts closed)

• Fault: De‑energized (contacts open) – triggers on power loss, module failure, or optical fault

5. Installation

5.1 Rack Mounting

1. Ensure Quantum rack power is OFF (or hot‑swap in powered rack).

2. Align module with rack slots, insert firmly until seated.

3. Secure with rack latch.

5.2 Cable Connections

Fiber Ports (ST)

• Tx → Rx of remote module; Rx → Tx of remote module.

• Cable: Multimode (50/125, 62.5/125, 100/140 µm).

• Min bend radius: 10× cable diameter.

Coaxial Port (BNC)

• Cable: 75 Ω (RG‑6 or equivalent).

• Max length: 100 m (copper segment).

5.3 Harsh Environment Notes

• The conformal coating protects against condensation, dust, and mild corrosives, but do not expose to direct liquid spray or immersion.

6. Configuration

• No manual configuration required: Module auto‑detects RIO S908 network.

• Software: Unity Pro V7.0 or later; add to I/O list, download project.

• Topologies: Point‑to‑point, dual redundant, multidrop (up to 31 drops).

7. Operation & Maintenance

Normal Operation

• READY: Green ON

• COM ACT: Green flashing

• OPT FAULT: Red OFF

• ERR: Red OFF

Troubleshooting

1. OPT FAULT ON:

   • Check Tx/Rx reversal, dirty/damaged connectors, tight bends, or wrong fiber type.

2. ERR ON:

   • Re‑seat module, check 5 V backplane power, replace module if fault persists.

3. READY OFF:

   • Verify rack power, check backplane short circuits.

Maintenance

• Quarterly: Inspect and clean ST connectors (isopropyl alcohol).

• Semi‑annually: Test diagnostic relay.

• Firmware: Update via Unity Pro (check Schneider Electric website).

8. Safety

• Qualified personnel only for installation/service.

• Disconnect power before rack maintenance.

• Laser safety: Class 1 LED (820 nm) – no eye hazard under normal use.

9. Ordering & Compatibility

• 140NRP95400C: Coated multimode, ST connectors.

• 140NRP95400: Non‑coated version.

• 140NRP95401C: Single‑mode alternative (LC duplex).
