Get now IC697PWR711 GE Fanuc Series 90-70 100W Power Supply
Get now IC697PWR711 to provide robust, uninterrupted electrical distribution to your critical PLC backplane infrastructure. The GE Fanuc IC697PWR711 is a high-performance 100-Watt Power Supply Module engineered exclusively for the Series 90-70 Programmable Logic Controller (PLC) system. This fundamental hardware component accepts a wide range of standard facility power—either 120 VAC or 240 VAC—and efficiently converts it into the precise +5 VDC, +12 VDC, and -12 VDC logic-level voltages required to drive the CPU, memory modules, and specialized I/O cards residing on the VME rack. Designed to operate reliably in harsh industrial environments, this OEM power supply incorporates advanced overvoltage and overcurrent protection circuitry, safeguarding your delicate processing hardware against catastrophic plant-floor voltage spikes and brownouts. By securing this essential module, you ensure maximum uptime and operational stability for your heavy-duty automation systems.

Installation Advice and Backplane Loading
When installing the IC697PWR711 into a Series 90-70 VME rack, precise load calculation is critical. Although this unit provides a substantial 100 Watts of total power, the majority of complex CPU modules and communication co-processors draw heavily from the +5 VDC rail. Before commissioning the system, manually calculate the cumulative current draw of all installed modules to ensure the 20-Amp limit of the +5 VDC output is not exceeded. Overloading the backplane will result in sudden voltage drops, triggering intermittent CPU resets and potentially corrupting SRAM memory. Furthermore, this specific power supply includes a connection terminal for external battery backup. To protect your logic programs during complete facility power failures, ensure that a fresh, verified lithium battery pack is securely wired to the designated terminal on the power supply chassis, allowing the system memory to bridge the power gap seamlessly.
Frequently Asked Questions (FAQs)
What does it mean if the OK LED on the IC697PWR711 is not illuminated? If the green OK LED is off while input power is applied, it indicates a critical internal failure or an overloaded backplane rail triggering the internal protection circuit. You must isolate the fault by removing I/O modules one by one; if the LED remains off with an empty rack, the power supply module has failed and requires replacement.
Does this power supply require manual voltage selection switching? No, the IC697PWR711 features universal input sensing and will automatically adjust to standard 120 VAC or 240 VAC input sources without the need for manual jumper configuration or selector switches.
Can I install two IC697PWR711 modules in a single rack for redundancy? The standard Series 90-70 architecture requires specialized redundant power supply modules and specific backplanes for true hot-standby redundancy. The standard IC697PWR711 is designed as a standalone primary power source for a single rack.
