Product Description

The IC697PWR721 designed by GE is a 24 VDC Power Supply Module with Adapter
. The module is intended for 90W with a nominal rated voltage of 24 volts DC. Input voltage ranges from +21 to +32 VDC and at a maximum load of 156 watts of input power. The IC697PWR721 can be attached to the left side of the rack, or it can be mounted as a stand-alone unit.
The IC697PWR721 module can be applied in a single rack application, but if the total load is within the supply rating, the module can be used to produce power to a second rack. Interconnections for the second rack are processed using a prewired cable. Protection is provided for both overcurrent and overvoltage fault conditions.

This power supply module must be connected to a Power Supply Adapter (IC697PWR720), which plugs into the power supply slot in an IC697CHS* rack. The PSA connects the power supply outputs to the IC697CHS* rack backplane and monitors the TTL signal, as well as the +5V, to deliver logic level sequencing signals to the backplane. The physical connection from the power supply to the PSA is through a cable connected to the power supply at the factory. As mentioned, the IC697PWR721 module operates from a 24 VDC power source, which can range from +21 to +32 VDC. This module is equipped with overvoltage protection, and outputs will be turned off by the circuit if voltage is exceeded. Once voltage is corrected, the power supply will reset automatically.

Customer Questions and Answers

  • Question:  What is an IC697PWR721?  Answer:  The IC697PWR721 is a 24 VDC, 90W Power Supply module with Adapter from the GE Fanuc 90-70 Series. 
  • Question:   What is special about IC697PWR721?  Answer:  This module is special because it can be attached to the left side of a rack OR it can be mounted as a stand alone unit. 
  • Question:   What power outputs does it provide?  Answer:  It provides +5 volt, +12 volt, and -12 volt regulated DC power outputs (as well as a TTL compatible logic shut-down signal).
  • Question:   What is this module comprised of?  Answer:  IC697PWR721 is comprised of the Power Supply (IC697PWR722) and the Power Supply Adapter (IC697PWR720).
  • Question:   What are some of the other features that IC697PWR721 provides?  Answer:
    • Operation from +21 VDC to +32 VDC
    • 3 regulated DC output voltages (90W total): +5 VDC output at 16.5 amps, +12 VDC output at 1.5 amps, and -12 VDC output at 1.0 amp
    • Mounts external to rack
    • Electronic short circuit overcurrent protection provided on all outputs
    • Input power fail and system reset signals
  • Question:   Can this unit only provide power to a single rack application?  Answer:  No. This unit can, yes, provide power to a single rack application, but it can also be used to provide power to a second rack (as long as the total load is within the supply rating).
  • Question:   What should be my next step if my IC697PWR721 is not working properly?  Answer:  Your IC697PWR721 may need to be repair
