GE Fanuc IC698PSA350B PACSystems RX7i Power Supply Module
The GE Fanuc IC698PSA350B, also cataloged as the IC698PSA350 power supply module, operates as a dedicated hardware component for multi-voltage DC power distribution within PACSystems RX7i platforms. It converts wide-range AC or DC field inputs into regulated backplane power rails (+5 VDC, +12 VDC, and -12 VDC) to drive VME64-based CPUs and I/O modules installed across RX7i racks.

VME64 Backplane Power Architecture & Thermal Profiles
The IC698PSA350B delivers regulated current directly to the RX7i VME64 backplane bus, supporting high backplane bus communication velocity across CPU and high-density I/O configurations. Delivering up to 60 A on the +5 VDC logic rail demands active thermal heat sink dissipation managed via a dedicated 70 CFM chassis fan tray. Internal firmware monitoring loops continuously poll airflow status and thermal thresholds to guarantee deterministic system execution while shielding internal backplane logic from line voltage fluctuations.
Frequently Asked Questions
Q: Can the IC698PSA350B module be installed in standard I/O slots inside an RX7i rack?
A: No, the IC698PSA350B features a keyway design restricted strictly to Slot 0 (the leftmost dedicated power supply slot) of the PACSystems RX7i main rack.
Q: What happens to power supply operations if the chassis fan tray experiences a mechanical fault?
A: The module incorporates active airflow monitoring. If cooling drops below required thresholds, the red OVER TEMP LED illuminates and internal protection circuits trip to shut down output rails before thermal damage occurs.
Q: How does Revision B differ from earlier hardware revisions regarding component protection?
A: Revision B updates the physical primary fuse specification to a standard 8 A, 250 V, 5 x 20 mm fuse format, replacing the legacy 0.25 in x 1.25 in fuse type used on earlier production builds.
Field Installation Guidelines
Slide the IC698PSA350B directly into Slot 0 of the RX7i rack along the card guide tracks until the backplane connectors seat completely. Tighten the top and bottom retaining screws to secure the unit against vibration. Connect source power using shielded wiring rated for at least 300 V, adhering to local electrical code specifications for AC (85 to 264 VAC) or DC (100 to 150 VDC) feeds. Ensure the 70 CFM fan tray operates continuously beneath the module card cage to facilitate vertical convection. Maintain a minimum clearance of 100 mm above and below the rack structure to prevent thermal recirculation and preserve ambient temperatures within 0 to 60 deg C.
