GE Corometrics 170 Series Mainboard Field Replaceable Unit with Signal Processing for Fetal Monitors

For all models in the 170 Series (171, 172, 173, 174), the mainboard handles these essential operations:

The mainboard acts as the central hub, connecting to all other major components within the monitor. System architecture diagrams from service manuals illustrate these critical connections.

In advanced models (173/174), the mainboard is engineered to work with a separate FECG/IUP Board that plugs directly into connectors J15 and J16, ensuring seamless integration and expanded monitoring capabilities.

Mainboard replacement requires detailed procedures that should only be performed by qualified service personnel. The process involves disconnecting all internal cables and transferring any optional boards. Replacement mainboards are available as Field Replaceable Units (FRUs) from GE HealthCare, typically through their core exchange program where defective boards are returned.
