Product Introduction
is the dedicated power supply for RX3i serial expansion racks that host legacy IC693 Series 90-30 I/O modules. These remote expansion racks connect to the main RX3i rack via IC695LRE001 serial transceiver and serial expansion cable.
Critical Platform Restriction
- : Only for IC694CHS790 serial expansion backplanes (remote Series 90-30 I/O racks).
- IC695PSA140 / PSD140: Main rack power supplies for IC695CHS007/012/016 RX3i main backplanes. They are not physically or electrically interchangeable.
Three output domains provide flexibility: 5V for backplane logic, non-isolated 24V for relay loads, and isolated 24V that can power field input sensors. The universal wide-range input supports global AC mains and industrial DC power systems.
Important: This module cannot drive RX3i native IC695 I/O modules; it is designed exclusively for remote Series 90-30 expansion racks.
QA & Testing SOP (Transparency Building)
- Incoming Inspection: Verify part marking; check backplane gold pins for oxidation/bending, inspect input terminal block and housing integrity.
- Live Testing: Mount onto validated IC694CHS790 expansion baseplate. Apply rated AC/DC input, verify all output voltage levels under resistive load, run continuous 24-hour stability test.
- Electrical Testing: Check output regulation and ripple; insulation resistance ≥10MΩ between input power circuit and chassis protective ground.
- Documentation: Photograph terminal wiring layout before disassembly; record hardware revision.
- Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming output stability validation prior to shipment.
Installation Pitfalls & Guide
❗ No Hot Swap Support: Power supply module cannot be hot swapped. Full expansion rack power shutdown mandatory before removal. ❗ Strict Baseplate Rule: Do not install into IC695CHS main RX3i backplanes; only IC694CHS790 serial expansion baseplate supported. ❗ 30W Total Power Budget: Sum all I/O module power consumption; total load cannot exceed combined 30W rating. ❗ Wiring Torque Control: Follow 1.3 N·m torque; loose terminals cause overheating and voltage drop. ❗ Isolated 24V Usage: Do not mix isolated 24V and non-isolated relay 24V on the same field circuit to avoid ground loops. ❗ Conformal Coated Variant Note: IC694PWR330CA = conformal coated for humid/corrosive environments; electrically identical to standard . ❗ ESD Risk: Static discharge damages primary switching circuitry leading to intermittent power dropout.
Replacement Guide
- Pre-install: Lockout-tagout expansion rack input power. Photograph terminal wiring and slot layout. Calculate total I/O power load.
- Removal: Disconnect AC/DC input wiring, unlatch module and slide straight out without twisting backplane pins.
- Install: Seat new into original slot on IC694CHS790, reconnect input power wiring with correct torque.
- Power-on Test: Restore input power; confirm PWR OK LED steady. Verify all remote Series 90-30 I/O modules are detected by main RX3i CPU.
FAQ
Q: Does support hot swapping? A: No. The power supply module cannot be hot swapped. Full rack power shutdown is required.
Q: Can I install on IC695CHS007 main RX3i rack? A: No. Mechanical and backplane bus incompatible. It is designed only for IC694 serial expansion baseplate.
Q: What is the difference between and IC695PSA140? A:
- : 30W, for serial expansion racks running Series 90-30 I/O
- IC695PSA140: Higher capacity main rack power supply for RX3i CPU & IC695 I/O modules Not interchangeable.
Q: What does IC694PWR330CA mean? A: -CA suffix = conformal coated PCB variant for harsh, high humidity/corrosive cabinet environments. Functionally identical.
Q: Can this power supply feed IC695 RX3i I/O modules? A: No. It only supports IC693 Series 90-30 I/O on serial expansion racks.
Q: Can multiple expansion racks share one ? A: Each expansion base requires its own dedicated power supply.
Q: Will I need any configuration after replacement? A: No software configuration for the power supply itself. After replacement, confirm all remote I/O points are scanned normally by the RX3i CPU.
