Product Introduction

is the high-capacity universal-input power supply for Series 90-30 main racks, designed for racks with high I/O density requiring larger 5V backplane power budget.

Important Power Supply Family Distinction

1. : Universal AC/DC wide input, high capacity 30W, main rack power supply
2. IC693PWR321: Standard capacity AC-input power supply
3. IC693PWR331: DC-only input high capacity power supply (equivalent IC693PWR330D)
4. IC694PWR330: Power supply for IC694 serial expansion racks (RX3i migration remote racks) These modules have different backplane interfaces and are not interchangeable.

Three separate output domains support flexible system design:

• 5VDC feeds CPU and all I/O module backplane logic
• Non-isolated 24V for relay output modules
• Isolated 24V for field sensor power to mitigate ground loop risks

Layout Rule: Must occupy the dedicated leftmost power slot; I/O/CPU modules cannot be installed in the power slot.

 

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking and hardware suffix. Inspect backplane gold pins for oxidation/bending; check input terminal block and housing integrity.
2. Live Testing: Mount onto validated IC693CHS backplane. Apply rated AC input power, test all three output rails under resistive load, monitor voltage regulation and ripple, run continuous 24-hour stability test.
3. Electrical Testing: Verify power trace continuity and ground bar; insulation resistance ≥10MΩ between input power circuit and chassis protective ground.
4. Documentation: Photograph terminal wiring layout before disassembly; document hardware revision.
5. Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming output voltage stability validation prior to shipment.

 

Installation Pitfalls & Guide

❗ No Hot Swap Support: Power supply module cannot be hot swapped. Full rack power shutdown mandatory before removal. ❗ Strict Baseplate Restriction: Only install on IC693CHS391 / CHS392 Series90-30 backplanes. Not compatible with IC694 or IC695 racks. ❗ Dedicated Leftmost Slot Rule: Only IC693 power supplies allowed in the first power slot. Never install CPU/I/O modules in the power slot. ❗ Total 30W Combined Power Budget: Sum consumption of all I/O modules; total load cannot exceed combined 30W rating. ❗ Grounding Guidance: Isolated 24V and non-isolated relay 24V circuits should not share common field grounds to avoid ground loops. ❗ Temperature Derating: Above 50°C cabinet temperature, reduce total 5V load to avoid over-temperature protection triggering. ❗ Revision Interchange: Base and suffix variants (-H, -J) are mechanically plug-compatible. After replacement, perform full rack I/O verification. ❗ ESD Risk: Static discharge damages switching power circuits leading to intermittent power dropout.

Replacement Guide

1. Pre-install: Lockout-tagout rack AC input power; back up complete PLC project. Photograph slot layout, input wiring and battery connection. Calculate total module power consumption.
2. Removal: Disconnect AC input wiring, unlatch module and slide straight out without twisting backplane pins.
3. Install: Seat new into original dedicated power slot, replicate AC input wiring connections.
4. Power-on Test: Restore rack power; confirm PWR OK LED steady. Verify all Series90-30 CPU and I/O modules are detected normally by programming software.

 

FAQ

Q: Does support hot swapping? A: No. Power supply module cannot be hot swapped. Full rack power shutdown required before removal.

Q: What is the difference between and IC693PWR331? A:

• : Universal AC/DC wide input
• IC693PWR331: DC-only 24V input version Electrical output specifications identical, input circuit different; cannot substitute if mains type mismatched.

Q: Can I install on IC695CHS007 RX3i main rack? A: No. Mechanical and backplane bus incompatible. It only works on native Series90-30 backplanes.

Q: Can multiple power supplies be fitted on one IC693CHS backplane? A: Only one dedicated power slot (leftmost slot); single power supply per rack.

Q: Will software configuration be needed after power supply replacement? A: No programming configuration required for the power supply itself. After replacement, confirm all I/O and CPU scan normally.
