The GE Fanuc IC697PWR711, also cataloged as the IC697PWR711 Power Supply Module, operates as a dedicated hardware component for power conversion and load distribution within Series 90-30 PLC platforms. The module accepts selectable input voltages of 120 VAC or 240 VAC through an external jumper setting to provide regulated direct current outputs and logic level sequencing across the system backplane.

The IC697PWR711 mounts into the leftmost position of a GE IC697 rack or a VME integrator rack, establishing physical pathways via a 48-pin backplane connector. While the supply does not require backplane bus communication velocity licences to perform its power conversion tasks, it executes precise hardware logic level sequencing signals directly toward the backplane to coordinate power-up and shutdown phases with the host CPU. The architecture allows for flexible I/O density scaling by supporting a 2-rack operation from a single supply unit, provided that the secondary chassis is joined via an approved 3-feet connecting cable and the net drawing current remains under 5.2 Amps.
Q: Can the IC697PWR711 be replaced or serviced while the PLC backplane is energized?
A: No. The IC697PWR711 requires full isolation of incoming field lines before extraction or installation. It features an integrated front-panel ON/OFF switch to manually activate or deactivate secondary outputs, but primary field power must be isolated externally before disconnecting the module.
Q: Does the module contain onboard protection circuits against output faults?
A: Yes. The module features internal electronic short-circuit and overcurrent protection loops. The hardware limits current peaks to 26 Amps on the +5 VDC line, 4 Amps on the +12 VDC line, and 2 Amps on the -12 VDC line to safeguard attached backplane modules from electrical damage.
Q: Under what conditions must the technical ratings of this power supply be derated?
A: For continuous operations in environments where high ambient temperatures and low line voltages occur simultaneously, the output specifications must be derated to ensure thermal profiles remain within safe tolerances.
