The GE Fanuc IC698PSA350, also cataloged as the IC698PSA350 Power Supply Module, operates as a dedicated hardware component for power conversion and regulated DC distribution within PACSystem RX7i networks. The unit accepts selectable AC or DC primary voltages to drive three distinct output rails across the VME backplane from its dedicated slot assignment.

The IC698PSA350 is engineered to support the high I/O density scaling profiles of RX7i processing racks, maintaining voltage regulation across the VME system interface under dynamic loads. To protect the processing environment against high-frequency transients, the module features a 1500 VDC isolation barrier between input terminals and all internal outputs. System integration remains highly predictable during brief line power drops, supported by a minimum hardware ride-through index of 15 milliseconds that ensures continuous processing without backplane resets.
Q: In which slot of the PACSystem RX7i rack must this power supply be installed?
A: The IC698PSA350 is physically keyed and electrically configured for dedicated installation in Slot 0 of the RX7i rack chassis.
Q: What type of wiring and terminals are required to connect the primary power and ground lines?
A: The input wiring terminals accommodate AWG #16 (1.3 mm2) conductors for lines and neutral, while the dedicated chassis ground terminal requires a heavier AWG #12 (3.3 mm2) conductor.
Q: What happens if an overcurrent condition occurs on the +5 VDC output rail?
A: The power supply features integrated hardware overcurrent protection. If the typical threshold limit of 66 Amps is breached on the +5 VDC rail, the protective loop will limit the output to prevent damage.
