ABB 3BHL000986P7000 LXN1604-6 LXN1604‑6 Light‑Net Fibre‑Optic Digital I/O Module for ACS6000 Medium‑Voltage Drive

1. Basic Information

2. Electrical & Interface Specifications

• Channel configuration: 16 digital input channels, 4 digital output channels
• Communication interface: Multiple fibre‑optic ports for Light‑Net serial communication
• Internal electrical side: 24 VDC logic level for control‑rack signals
• Optical side: Galvanic isolation between low‑voltage control rack and high‑voltage power modules
• Main function: Transfer binary commands, status feedback and fault signals between main controller and power units
• No analog signal processing; only discrete digital signal transmission
• Diagnostics: Channel fault detection, optical link loss monitoring with LED indication

3. Environmental Conditions

• Operating temperature: 0 ℃ ~ +55 ℃ (inside converter cabinet)
• Storage temperature: ‑40 ℃ ~ +85 ℃
• Relative humidity: 5‑95 % RH, non‑condensing

• Enclosure rating: IP00 (module installed inside protected cubicle)
• Mechanical: Standard 19‑inch rack plug‑in board format for ACS6000 control cabinet

4. Main Functions

1. Light‑Net digital I/O module acting as optical‑electrical signal interface for ACS6000 medium‑voltage drive.
2. Receives status and fault feedback signals from power modules via fibre optics; transmits control commands from main controller to power hardware.
3. Provides complete galvanic isolation between high‑voltage power section and low‑voltage control electronics, suppressing EMI and ground potential differences.
4. Monitors fibre‑optic link health and channel status; reports failures to the drive main control unit.
5. Works cooperatively with other Light‑Net series boards inside ACS6000 control rack.
6. Product lifecycle status: End‑of‑Life, ABB discontinued new production; procure spares with complete part number.

5. Typical Applications

1. Signal interface inside ABB ACS6000 medium‑voltage variable‑frequency drives for compressors, fans, pumps in petrochemical, power and mining industries.
2. Optical isolation of control signals between high‑voltage power modules and low‑voltage control rack.

6. Important Notes

1. This module is dedicated to ACS6000 drive Light‑Net system; cannot be used as general‑purpose optical I/O for external PLC/DCS.
2. Fibre‑optic cables must be kept clean and undamaged; dirty or bent fibres will trigger link‑loss faults.
3. Operates on 24 VDC auxiliary supply; over‑voltage will damage board electronics.
4. All commissioning and fault diagnosis shall use ACS6000 drive tool software.
5. Full ordering part‑number 3BHL000986P7000 must be used for spare‑part purchasing.
