Product Description

Avalon FM20/FM30 Fetal Monitor Drive Board PN M2703-66430 In Good Condition

It is important to clarify that in the context of the Avalon FM20/FM30 fetal monitors, the term "drive board" is generally not an official, singular component name. Instead, the monitor contains several specific printed circuit board assemblies (PCBs) that perform driving or control functions.

Key Circuit Board Components

Main Board (Motherboard)

Part Number	M2705-66410 (also listed under 451261009061)
Function	Controls all primary monitor operations, including signal processing from the fetal probes (ultrasound, TOCO), maternal vital signs modules, and the overall user interface. This is the core logic board.
Application	If the monitor fails to boot, has corrupted graphics, or is unresponsive, this is the primary suspect.

Power Supply Unit (PSU) / Power Board

Part Number	Part of the M4605A / M8023A series (External)
Function	This is a wide-range switching power supply. It automatically accepts input from 100V to 240V (±10%) at 50/60 Hz and converts it to the necessary DC voltages (primarily 24V output) to run the main board, display, and thermal recorder.
Application	Used for "No Power" or "Intermittent Shutdown" issues.

Connector Board (Sensor Interface)

Part Number	M2703-26420 / M2703-66420
Function	This board acts as the physical interface gateway. It is the board where the fetal sensors (TOCO, Ultrasound) and patient cables plug into the front of the monitor.
Application	If specific sensors are not being detected (e.g., "Probe Disconnected" error) but the rest of the monitor works, this board may be faulty.

Touch Panel Controller Board

Part Number	M2703-26440
Function	This is the closest equivalent to a "Touch Drive Board." It controls the touchscreen overlay. It translates your touch inputs into digital signals for the Main Board.
Application	If the display works (shows waveforms/numbers) but the screen does not respond to touch, this specific driver board is likely the issue.

Technical Summary for Repair

Power Compatibility: The monitor does not require manual voltage selection; the power supply is auto-sensing.
Safety Class: The FM20/30 is a Class II device (double insulated), meaning it does not rely on a protective earth ground for safety, though grounding is required for EMC compliance.
