GE IC698PSA350 Maintenance-Ready Spare for RX7i Automation
The GE IC698PSA350 is a 350W AC input backplane power supply module designed for the PACSystems RX7i rack-based control platform. In industrial environments where continuous operation is non-negotiable, maintaining a verified spare of the IC698PSA350 is a foundational element of any credible maintenance strategy. Power supply failures are among the leading causes of unplanned PLC downtime, and the IC698PSA350 — as the primary energy source for the RX7i backplane — is a single point of failure that demands proactive spare parts coverage.
This original GE Automation & Controls module delivers regulated DC power to all modules seated in the RX7i 17-slot or 9-slot backplane, including CPU modules such as the IC698CPE020 and IC698CPE030, as well as co-processor and communications modules. Its 350W capacity supports fully populated racks with mixed I/O, motion, and communications modules, making it the preferred choice for high-density control cabinet configurations in process, discrete, and hybrid manufacturing environments.
Each unit supplied by SMARTNEXMSK is sourced from verified channels, subjected to pre-shipment functional testing, and dispatched with a 12-month warranty. Our inventory is maintained to support both planned maintenance cycles and emergency replacement scenarios, with same-week shipping available for in-stock units.

Maintenance Planning for Continuous Operation
When a maintenance or reliability engineer schedules a planned inspection or responds to a power fault alarm on a PACSystems RX7i system, the IC698PSA350 is rarely the only component that warrants attention. A disciplined maintenance approach treats the power supply replacement as an opportunity to audit the entire control cabinet for aging or marginal components.
During the same maintenance window, engineers should verify the condition of the IC698CHS017 backplane — connector wear and backplane bus degradation are common in systems with 8+ years of service. The IC698CPE030 CPU module battery should be checked and replaced if the low-battery LED is active, as loss of battery backup can corrupt the user program on power cycle. If the cabinet includes a IC698ETM001 Ethernet communications module, inspect its RJ45 port and verify network connectivity post-restart, as power interruptions can corrupt module configuration.
For I/O-intensive racks, inspect IC694MDL654 discrete output modules and IC694ALG220 analog input modules for signs of thermal stress or field wiring damage. Relay output modules in particular — such as the IC694MDL940 — should be checked for contact wear if they are switching inductive loads. Terminal blocks and field wiring connectors on I/O modules should be re-torqued to specification during any power supply replacement event.
If the RX7i system communicates over Profibus or DeviceNet, the IC698PBM300 Profibus Master module should be verified for correct baud rate and node addressing after power restoration. Signal isolators on 4–20mA analog loops feeding the RX7i should also be inspected — a marginal isolator can introduce noise that mimics sensor faults after a power event. Fuse holders and DIN-rail mounted circuit breakers feeding the IC698PSA350’s AC input should be tested for continuity and replaced if showing signs of heat discoloration.
For sites running redundant RX7i configurations, the IC698RMX016 redundancy memory xchange module and its fiber-optic interconnect should be inspected to confirm synchronization status is restored within expected timeframes after the power supply swap.
Site Replacement Workflow
Replacing the IC698PSA350 in a live production environment requires a structured approach to minimize downtime and avoid configuration loss. Begin by exporting the current CPU program and hardware configuration using Proficy Machine Edition (PME) before de-energizing the rack — this ensures a recovery baseline is available if the CPU loses its program during the power interruption.
De-energize the AC input feed to the power supply using the upstream circuit breaker or disconnect. Verify zero voltage at the AC input terminals with a calibrated multimeter before proceeding. The IC698PSA350 is installed in Slot 0 of the RX7i backplane and is secured with captive screws — remove these and slide the module straight out along the backplane guide rails. Inspect the backplane connector for bent pins or debris before installing the replacement unit.
Seat the new IC698PSA350 firmly into Slot 0, secure the captive screws to the specified torque, and reconnect the AC input wiring. Re-energize and observe the module’s status LEDs: the OK LED should illuminate green within 3 seconds of power application. If the CPU does not return to RUN mode automatically, use PME to download the saved configuration and verify I/O module status in the hardware configuration tree.
For sites migrating from older GE Series 90-70 power supplies, the IC698PSA350 is the direct RX7i-generation replacement and is not backward-compatible with Series 90-70 backplanes. Confirm backplane model before ordering. SMARTNEXMSK can assist with compatibility verification prior to shipment to eliminate the risk of receiving an incompatible module.
Spare Parts Support FAQ
Q1: Is the IC698PSA350 still available as a new original spare, or only as refurbished stock?
SMARTNEXMSK maintains inventory of original GE IC698PSA350 units sourced from authorized distribution and verified surplus channels. Each unit undergoes pre-shipment functional testing. Condition and origin are disclosed at the time of quotation. A 12-month warranty applies to all units shipped.
Q2: How do I confirm compatibility with my existing RX7i backplane before ordering?
The IC698PSA350 is compatible with IC698CHS017 (17-slot) and IC698CHS009 (9-slot) RX7i backplanes. Provide your backplane part number and rack configuration when contacting us — our technical team will confirm compatibility and advise on any firmware or hardware revision considerations before shipment.
Q3: What is the recommended spare parts strategy for IC698PSA350 in a critical production line?
For single-rack RX7i systems in critical applications, we recommend maintaining one cold spare IC698PSA350 on-site. For multi-rack or redundant configurations, a ratio of one spare per three installed units is a common industry practice. Power supplies have a finite capacitor service life (typically 7–10 years at rated temperature), so proactive replacement on a scheduled basis is preferable to reactive replacement after failure.
Q4: Does SMARTNEXMSK provide pre-shipment testing documentation for the IC698PSA350?
Yes. All IC698PSA350 units are powered-on tested prior to shipment. A test report confirming output voltage regulation within GE specification is available upon request. Units are packed in anti-static packaging with appropriate cushioning for international freight. Lead time for in-stock units is typically 3–5 business days to most destinations.
