Product Introduction
The IC698PSA350D is a high-capacity 350W AC/DC power supply module for the GE PACSystems RX7i platform. It is not a CPU module, not an I/O module, and not compatible with other GE series such as Series 90-70, RX3i, or VersaMax. Its sole function is to convert wide-range AC or DC input power into regulated +5 VDC, +12 VDC, and -12 VDC rails that feed the RX7i backplane and all installed CPU, communication, and I/O modules.
This module must be installed in Slot 0 — the leftmost position — of the RX7i universal rack. Unlike the lower-capacity IC698PSA100 (100W, no forced cooling required), the IC698PSA350 series requires a 70 CFM chassis-mounted fan for forced-air cooling. If airflow is interrupted or the internal temperature exceeds limits, the OVER TEMP LED illuminates and the module may shut down to protect itself and the backplane.
The module accepts a universal input range of 85-264 VAC (47-63 Hz) or 100-150 VDC, making it suitable for global installations without hardware changes. It features active power factor correction (0.99 PF on AC), 1500 VDC isolation between input and outputs, and can ride through up to one AC line cycle of power loss without dropping the DC outputs.
QA/QC Transparency SOP
- Intake & Origin Verification — Record full model IC698PSA350D, series revision (A or B), serial number, and physical condition. Verify fuse type matches the series: Series A uses 0.25″ x 1.25″ fuses; Series B uses 5x20mm fuses (typically 8A/250V). Reject units with burnt components, damaged terminal blocks, or missing labels.
- Input Voltage Testing — Apply 120 VAC, 240 VAC, and 125 VDC separately. Verify stable power-up, correct LED behavior (FIELD OK and OUTPUT OK illuminated, OVER TEMP off), and no abnormal noise or odor.
- Output Voltage Regulation — Measure +5 VDC, +12 VDC, and -12 VDC rails under no-load and loaded conditions. Verify voltages are within RX7i specification. Check over-voltage protection trip point on the +5 VDC rail (5.7-6.7 VDC range).
- Protection Circuit Verification — Test over-temperature shutdown by simulating airflow restriction. Verify short-circuit and over-current protection on each output rail. Confirm the module recovers correctly after fault clearance.
- Backplane Integration Test — Install in an RX7i test rack with a known-good CPU and I/O modules. Verify backplane communication, module recognition, and stable operation over an extended burn-in period.
- Final QC & Anti-Static Packaging — Seal in ESD bags with desiccant. Include test report, nameplate photos, series/fuse type record, output voltage measurements, and a “verify with GE/Emerson RX7i manual before installation” warning.
Field Engineer Gotchas
- Slot 0 only. The IC698PSA350D must be installed in the leftmost slot (Slot 0) of the RX7i rack. It will not function in any other slot position.
- Forced cooling is mandatory. Unlike the 100W IC698PSA100, the 350W unit requires a 70 CFM chassis fan. A failed or blocked fan triggers the OVER TEMP LED and can cause shutdown.
- Series A vs. B fuse difference. Series A uses 0.25″ x 1.25″ fuses; Series B uses 5x20mm fuses. Replacing a blown fuse with the wrong size or rating can cause repeated failures or safety hazards.
- Not compatible with RX3i or Series 90-70. This is an RX7i-specific power supply. It will not fit or function in RX3i (IC695PSA012/PSA040) or Series 90-70 racks.
- Total output is 350W across all rails. The +5 VDC, +12 VDC, and -12 VDC outputs share the 350W budget. Heavy +5 VDC loading (e.g., many I/O modules) can limit available +12 VDC/-12 VDC current. Always perform a backplane power budget calculation before adding modules.
- The “D” suffix matters. IC698PSA350, , and IC698PSA350E may have different internal revisions, firmware, or fuse configurations. Do not assume interchangeability without OEM confirmation.
- DC input range is 100-150 VDC, not 24/48 VDC. This module does not accept low-voltage DC inputs. For 18-30 VDC applications, the RX7i IC698PSD300 is the correct module.
GE IC698PSA350D
Application Scenarios
- RX7i large-scale PLC rack power-up. Provides 350W backplane power for an RX7i rack loaded with a redundant CPU pair, multiple Ethernet/IP communication modules, and dense digital/analog I/O.
- Global installation with wide AC input. A single SKU supports 85-264 VAC, simplifying spare parts inventory for multinational sites with 120 VAC and 240 VAC regions.
- DC-fed control room installation. In facilities with a 125 VDC station battery system, the module accepts 100-150 VDC input directly, eliminating the need for an external AC/DC converter.
- Brownfield RX7i power supply replacement. Replaces a failed IC698PSA350 or during a planned outage, with series revision and fuse type verified against the existing rack configuration.
FAQ
No. It is designed exclusively for the PACSystems RX7i universal backplane. RX3i uses different power supply modules (e.g., IC695PSA012, IC695PSA040).
Can I install it in any slot?
No. It must be installed in Slot 0 (leftmost slot) of the RX7i rack.
Does it require a fan?
Yes. The 350W module requires a 70 CFM forced-air chassis fan. The 100W IC698PSA100 does not.
What is the difference between Series A and Series B?
The fuse type: Series A uses 0.25″ x 1.25″ fuses; Series B uses 5x20mm fuses (typically 8A/250V).
Can it run on 24 VDC?
No. The DC input range is 100-150 VDC. For 18-30 VDC, use the IC698PSD300.
What does the “D” suffix mean?
It denotes a specific revision/variant of the IC698PSA350. Verify the exact label against your installed hardware, as revisions may differ in fuse type, internal components, or firmware.
Where can I get the official manual?
Request the PACSystems RX7i hardware manual from Emerson Automation (which acquired GE Intelligent Platforms). Do not rely solely on third-party vendor pages, which sometimes list incorrect power ratings or compatibility information.
