Product Details 

IC697PWR748D is a 90‑watt DC‑input rack power supply for GE Fanuc Series 90‑70 PLC control system, revision D hardware version, designed for industrial sites with 48VDC field power supplyQualitrol.

This power module must be inserted into the left‑most dedicated power slot of the 90‑70 main chassis. It delivers +5VDC, +12VDC and‑12VDC multi‑rail DC power for CPU, I/O boards and other plug‑in modules via 48‑pin backplane connector. It supports wide‑range 35‑60VDC DC input, adapting to fluctuation of industrial 48V DC power network.

The +5V bus adopts electronic short‑circuit and over‑current protection, with built‑in over‑voltage clamping circuit. When abnormal voltage occurs, it clamps voltage below 6.7V to avoid burning core logic modules on the backplane. Full‑load hold‑up time reaches more than 10ms, providing short‑time data protection against momentary power dip.

Within allowable load range, one IC697PWR748D can supply power for two racks simultaneously, reducing hardware investment for multi‑rack projects. It outputs power‑good sequential logic signals to the backplane, ensuring orderly power‑on and power‑off sequence for each module. Front‑panel LED directly shows power running status for quick on‑site inspection.

Slide‑in rack‑mount structure brings convenient installation and replacement. Natural convection cooling makes it run reliably under 0‑60℃ environment without fan. Widely used in power, petrochemical and heavy‑industry fields for maintenance, upgrade and spare‑part replacement of old Series 90‑70 PLC automation racks.
