Product Introduction
is a universal-input power supply for Series 90-30 PLC, designed for machine and process control cabinets. The most prominent feature among the Series90-30 power supply lineup: integrated RS485 diagnostic port, allowing the CPU or monitoring system to read power supply operating status, fault information and load conditions.
Important Power Supply Family Comparison
- : Universal AC/DC input, equipped with diagnostic communication
- IC693PWR330: Universal AC/DC input,
- IC693PWR331: DC-only input high capacity power supply
- IC693PWR321: Standard AC input, lower power budget All above modules share identical mechanical form factor, physically interchangeable, but communication function differs.
Three independent output domains support flexible field design:
- 5VDC powers CPU and all I/O module backplane logic
- Non-isolated 24V for relay output modules
- Isolated 24V for field sensors to mitigate ground loop risks
Layout Mandate: Must install in the leftmost dedicated power slot; CPU and I/O modules cannot be fitted into the power slot.
QA & Testing SOP (Transparency Building)
- Incoming Inspection: Verify part marking. Inspect backplane gold pins for oxidation/bending; check input terminal block and housing integrity.
- Live Testing: Mount onto validated IC693CHS backplane. Apply rated AC input power, test all three output rails under resistive load, verify diagnostic communication, run continuous 24-hour stability test.
- Electrical Testing: Monitor backplane 5V rail stability. Insulation resistance ≥10MΩ between input power circuits and chassis protective ground.
- Firmware Record: Document hardware revision; photograph terminal wiring layout before disassembly.
- Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming output stability and diagnostic communication 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 IC693CHS Series90-30 backplanes. Not compatible with IC694 expansion racks or IC695 RX3i main racks. ❗ Dedicated Leftmost Slot Rule: Slot0 exclusively for power supply modules. Never install CPU/I/O modules in the power slot. ❗ Wiring Guidance: If utilizing diagnostic port, use shielded twisted pair cable; avoid parallel routing with high-power AC wiring. ❗ Total 30W Combined Power Budget: Sum all I/O module power consumption; total load cannot exceed combined 30W rating. ❗ Grounding Design: Isolated 24V and non-isolated relay 24V circuits should not share common field ground to avoid ground loops. ❗ Temperature Derating: Above 50°C ambient temperature, reduce total 5V load to prevent over-temperature protection. ❗ ESD Risk: Static discharge damages switching power circuits and transceivers, leading to intermittent power or communication faults.
Replacement Guide
- Pre-install: Lockout-tagout rack power; back up complete PLC project. Photograph slot layout, AC input wiring and battery connection. Calculate total module power consumption.
- Removal: Disconnect AC input wiring, unlatch module and slide straight out without twisting backplane pins.
- Install: Seat new into original dedicated power slot, replicate input wiring connections and confirm battery installation.
- Power-on Test: Restore rack power; confirm PWR OK LED status, verify all CPU and I/O modules are detected normally, test diagnostic port if utilized.
FAQ
Q: Does support hot swapping? A: No. The power supply module cannot be hot swapped. Full rack power shutdown required before removal.
Q: What is the key difference between and IC693PWR330? A: Form factor and power ratings identical.
- : Built-in diagnostic communication port
- IC693PWR330: No onboard diagnostic port Mechanically interchangeable; projects requiring power supply monitoring cannot directly substitute PWR330 for PWR324.
Q: Can I install into RX3i IC695CHS007 main rack? A: No. Mechanical and backplane bus incompatible. It is native Series90-30 power supply.
Q: Can multiple power supplies be fitted on one IC693CHS backplane? A: Only one dedicated power slot (Slot0); single power supply per rack.
Q: Does the port replace CPU programming port? A: No. This is dedicated power supply diagnostic monitoring, cannot be used for PLC program download.
Q: Will PLC program need modification after power supply replacement? A: No program changes required unless the project uses power supply diagnostic data via .
