GE Fanuc IC697PWR720 – Series 90-70 Rack Power Supply for Reliable PLC Backplane Power

The GE Fanuc IC697PWR720 is a dedicated power supply module for the Series 90-70 (IC697) PLC racks. From my experience, it’s the go-to choice when you need stable, clean backplane power for a mix of CPU and high-density I/O in heavier applications—think metal forming lines, large packaging machines, or process skids that run 24/7. You might notice that it’s built for long service life and predictable behavior, which typically translates into fewer nuisance trips and less time chasing power-related faults.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Designed for Series 90-70 racks – Slides into the standard IC697 power bay and feeds the entire backplane reliably.
• Auto-ranging AC input – Typically supports 100–240 VAC at 50/60 Hz, making it straightforward for global panels.
• Stabilized backplane power – Provides regulated logic power for CPU and I/O; in many cases helps reduce intermittent logic resets under heavy loads.
• Status indication – Front LEDs for quick checks of power presence and fault state; technicians usually spot issues faster during shift turnovers.
• Built-in protections – Overcurrent and overvoltage protection to guard the rack electronics in abnormal conditions.
• Service-friendly form factor – Standard single-slot module depth and captive front screws; fast swap-out during planned downtime.

Technical Specifications

Related or Supporting Products

• IC697PWR711 – AC input power supply for Series 90-70; typically lower capacity compared with high-load variants.
• IC697PWR713 – High-capacity AC input supply, often chosen when I/O count and inrush demands are higher.
• IC697PWR724 – 24 VDC input version, useful where a DC bus is already available in the cabinet.
• IC697CHS750 / IC697CHS790 – Series 90-70 racks (various slot counts) that accept the IC697PWR720.
• IC697CPU772 / IC697CPU781 – Compatible CPUs commonly paired with this power supply in legacy systems.

Installation & Maintenance

• Cabinet & ventilation – Mount in a clean, dry enclosure with adequate airflow. Leave space above/below the rack; avoid heat sources immediately beneath the power bay.
• Wiring – Use a dedicated, properly rated branch circuit with protective earth. Typical L/N/PE termination for AC input; keep AC and control wiring segregated.
• Derating & load planning – In most cases, high ambient temperatures or heavy startup inrush from solenoids and relay banks call for margin on the supply capacity.
• Safety – De-energize and lockout/tagout before installation or replacement. Allow time for internal capacitors to discharge.
• Routine checks – Inspect connectors and mounting screws quarterly, clean dust with dry air, and verify LED status. No calibration is required; just keep an eye on load growth after I/O expansions.

Customer feedback we hear often: “Once we swapped to the IC697PWR720, the random CPU resets during heavy shifts stopped.” That seems to be the typical outcome when the previous supply was marginal for the load.
