Mortara ELI 250 ECG Machine Mainboard Assembly 5525-039-03A 26025-039-51 Mother Board for Medical Equipment
■ Product Describe
The Mainboard Assembly 5525-039-03A/26025-039-51 of Mortara ELI 250 ECG Machine is the core control center of the device, integrating signal processing, data management and system communication functions to ensure the efficient operation of ECG acquisition, analysis and output. The mainboard assembly includes several key hardware components, including core processor, front-end circuit (reducing common-mode interference through differential amplifier, supporting 0.05-300Hz wide frequency response range), ADC module (20-bit resolution, ensuring accurate capture of tiny signals (such as pacing spikes).
), communication module (built-in Wi-Fi (supports WEP/WPA/WPA2 encryption) and Ethernet interface, which can realize wireless data transmission and remote consultation, and inform diagnosis and treatment efficiency), etc.
■ Product Picture
■ Functions
1. Signal processing and analysis
The mainboard receives the patient's ECG signal from 12-lead monitoring, and converts the ECG signal into a waveform that can be displayed on the display screen through an analog-to-digital converter, as well as a diagnostic report generated based on age- and gender-specific standards for reference by medical staff
2. System control
Coordinate key input (such as Key Membrane), display update, print instructions and other operations to ensure real-time response (signal delay < 10ms).
3. Data management
The mainboard has a built-in storage module that supports 60 ECG records (expandable to 150), and data export is achieved through USB or network interface.
4. Communication hub
Integrates multiple interfaces (USB, LAN, WLAN, Modem, RS232), supports DICOM protocol and two-way data transmission, and seamlessly connects to medical systems such as PACS and EMR.

■ Precautions for use
Operation specification:
Static protection: Wear an anti-static wristband when replacing the motherboard to prevent static electricity from damaging sensitive components (such as processors, ADCs).
Configuration synchronization: Before replacement, you need to export the configuration file (such as lead calibration parameters) through the motherboard setting interface, and re-import it after the new motherboard is installed to ensure normal function.
Maintenance:
Cleaning method: Use a lint-free cloth dipped in 70% isopropyl alcohol to wipe the surface. Ammonia-containing cleaners are prohibited (may corrode the PCB coating).
Contact inspection: Check the gold fingers of the FPC interface every quarter. If there is oxidation, clean it with an eraser to ensure stable signal transmission.
Environmental management:
Temperature and humidity control: Avoid using in an environment with a temperature of ＞40°C or a humidity of ＞90% to prevent capacitor bulging or solder joint cracking.
Electromagnetic isolation: Keep a distance of ≥2 meters from the MRI equipment to avoid strong magnetic fields interfering with ADC signals.
