Product Introduction

This unit supplies stable multi-domain power for Series 90-30 racks designed for mains AC or high-voltage DC plant power. It distributes logic power to the backplane and provides separate 24V supplies for relay outputs and discrete field I/O modules.

Flexible power allocation allows the full 30W capacity to be allocated to the +5VDC rail for racks with high CPU and I/O density. The universal input eliminates jumper adjustments for global mains voltage variants, common for overseas machine exports and plant retrofits.

QA & Testing SOP (Transparency Building)

1. Incoming Inspection: Verify part marking and hardware revision suffix. Inspect edge connector pins for bending or corrosion; check terminal block housing for cracks.
2. Live Testing: Mount to validated Series 90-30 backplane, apply nominal AC input. Load all output rails and monitor voltage stability through a continuous 24-hour run cycle.
3. Electrical Testing: Use Fluke 115 to track rail regulation. Insulation resistance testing must exceed 10MΩ between input terminals and chassis protective ground.
4. Documentation Check: Record hardware revision. Photograph input wiring layout before disassembly.
5. Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag listing steady-state voltage readings prior to shipment.

Installation Pitfalls & Guide (Engineer to Engineer)

❗ No Hot Swap Support: Series 90-30 backplanes lack hot-swap bus logic. Live removal crashes all rack modules and risks permanent backplane trace damage. Full rack power shutdown mandatory. ❗ Slot Placement Mandate: Install only in the far-left dedicated power slot (Slot 0). Insertion into regular I/O slots prevents backplane power distribution and will not operate. ❗ Input Type Confusion: This universal AC/DC input module cannot be directly swapped with IC693PWR331 (24VDC input). Mismatched input power will destroy the power supply. ❗ ESD Dangers: Exposed backplane connector circuits are static-sensitive. Un-grounded handling can create drifting output regulation that appears after commissioning. ❗ Power Budget Miscalculation: Sum total power draw of all installed modules. Overloading the 30W total rating creates voltage sag, random CPU faults and intermittent module dropouts.

Replacement Guide:

1. Pre-install: Activate lockout-tagout on rack input power; document all input wiring connections.
2. Removal: Disconnect AC/DC input terminals, unlatch module and slide straight out without twisting edge connectors.
3. Install: Seat new unit fully into Slot 0, lock latches, terminate input wiring and verify torque on terminal screws.
4. Power-on Test: Restore input power, confirm Power OK LED illuminates; power up CPU and verify all I/O modules are recognized by programming software.

FAQ (Frequently Asked Questions)

Q: Does this unit support hot swapping? A: No. The Series 90-30 backplane architecture does not support live power supply removal. Full rack power shutdown is required for replacement.

Q: What is the difference between and IC693PWR331? A: accepts universal 85–264VAC / 100–300VDC input. IC693PWR331 is designed for 24VDC nominal input. They are not direct interchangeable. Confirm site power source before replacement.

Q: Can this power supply be used inside RX3i racks? A: No. Form factor, pinout and signaling are exclusive to Series 90-30 chassis. It cannot operate within PACSystem RX3i hardware.

Q: Can multiple power supplies run in parallel for redundancy? A: Load sharing and redundant parallel operation are not supported. Each rack requires one dedicated power supply. Deploy separate racks for fault-tolerant layouts.

Q: What happens during a short-circuit on any output rail? A: The supply triggers auto-recovering current limiting. Persistent faults will assert the Fault LED and halt output regulation until input power is cycled.

Q: Can I use this unit on Series 90-30 remote expansion racks? A: Yes, it is compatible for expansion baseplates, provided the rack is configured to accept this universal input power supply. Confirm rack power budget before loading I/O modules.

Q: Will a replacement unit work without configuration changes? A: No software configuration is required for power supplies. After installation, verify all rail voltages and monitor for intermittent fault codes caused by overloaded backplane loads.
