Product Introduction
The ABB LXN1604-6 is a DIN-rail power supply commonly used to provide a stable 24 VDC control voltage for industrial automation systems. It is typically installed in control cabinets to power PLCs, DCS I/O racks, sensors, relays, actuators, and other low-voltage control devices.
The module is associated with ABB order code 3BHL000986P7000 and is listed by multiple distributors as a 200–240 VAC input, 24 VDC / 6 A, 144 W DIN-rail power supply. Because public listings do not include a complete OEM datasheet, the exact mechanical dimensions, efficiency, derating curve, and approval marks should be confirmed from the unit nameplate or ABB documentation before replacement.

QA/QC Transparency SOP
- Nameplate Verification
Confirm ABB branding, model LXN1604-6, order code 3BHL000986P7000, serial number, input/output ratings, and manufacturing date. Check for heat damage, swollen capacitors, burnt terminals, or cracked housing. - Visual & Mechanical Inspection
Inspect DIN-rail clip, terminal blocks, screw torque marks, ventilation slots, and LED indicators. Verify that the unit has not been dropped or exposed to moisture beyond its rated IP class. - Input Power Test
Apply rated AC input voltage. Verify normal startup, absence of abnormal noise, and correct LED status. Measure input current under no-load and load conditions. - Output Performance Test
Measure 24 VDC output voltage under no-load, half-load, and full-load conditions. Check voltage regulation, ripple, and stability. Verify overload and short-circuit protection behavior if test equipment allows. - Final Documentation & Packaging
Record input/output readings, protection test results, serial number, and observed condition. Pack with anti-static and moisture protection. Label clearly to avoid confusion with ABB I/O modules or drive components.
Field Engineer Gotchas
- Misidentified product type
Risk: Some listings describe LXN1604-6 as an I/O module, digital input module, or power converter.
Fix: Confirm the order code 3BHL000986P7000 and the nameplate ratings.
Warning: If the label shows 24 VDC / 6 A output, it is almost certainly a power supply, not an I/O card. - IP65 rating may not apply to all installations
Risk: IP65 appears in some distributor descriptions, but it may depend on terminal covers and mounting conditions.
Fix: Check the actual unit label and installation environment.
Warning: Do not assume IP65 protection if terminal covers are missing or damaged. - Input voltage range mismatch
Risk: Some sources list 100–240 VAC, while others list 200–240 VAC.
Fix: Use the nameplate rating as the final authority.
Warning: Applying 110 VAC to a 200–240 VAC-only unit may prevent proper startup. - Insufficient load capacity
Risk: Adding new instruments or relays can push the 24 VDC bus beyond 6 A.
Fix: Calculate total 24 VDC load before replacement.
Warning: A power supply that trips intermittently is often overloaded, not defective. - Assuming hot-swap capability
Risk: Not all DIN-rail power supplies are designed for live replacement.
Fix: Follow plant lockout/tagout procedures and isolate downstream loads if required.
Warning: Removing a live supply can disturb PLC, DCS, or safety circuits.

Application Scenarios
- PLC and DCS control power
Provides 24 VDC for CPU racks, I/O modules, communication modules, and control relays. - Instrumentation and sensor supply
Powers pressure, temperature, flow, and level transmitters that require a stable 24 VDC loop supply. - Control cabinet retrofit
Replaces failed DIN-rail power supplies where the input voltage, output rating, and mounting footprint match. - Machine skid power distribution
Used on packaged equipment to convert AC mains into a clean 24 VDC control voltage.
FAQ
What is ABB LXN1604-6?
It is an ABB DIN-rail power supply, order code 3BHL000986P7000, commonly listed as 200–240 VAC input and 24 VDC / 6 A output.
Is LXN1604-6 an I/O module?
Some aftermarket listings describe it as an I/O or digital input module, but the order code and most distributor data point to a DIN-rail power supply. Always confirm on the physical nameplate.
What output does it provide?
24 VDC at 6 A, 144 W, based on common distributor listings.
Can it accept 110 VAC input?
Not confirmed. Some sources list 100–240 VAC, others list 200–240 VAC. Use the unit nameplate as the final reference.
Is it IP65 rated?
IP65 appears in some listings, but this should be verified on the actual product label and terminal cover configuration.
Can it power a PLC system?
Yes, if the total 24 VDC load stays within 6 A and the input voltage matches the site supply.
Do you provide calibration certificates?
Power supplies are typically verified by output voltage, load regulation, and protection tests rather than calibration certificates. Request test logs for refurbished units.
