Mortara ELI 250 ECG Machine Keypad Board 5525-040-02B 26025-040-51 Good Condition Medical Parts
■ Product Describe
Keypad Board 5525-040-02B/26025-040-51 is the printed circuit board (PCB) of the ELI 250 ECG machine. It integrates key circuits, signal processing modules and interfaces. It is the core control circuit component of the Mortara ELI 250 ECG Machine. As the "nerve center" of the keyboard system, it is responsible for converting physical key actions into electrical signals and transmitting them to the motherboard.
It has high reliability and accurate signal processing capabilities to ensure efficient and safe medical operations. Its IP protection, anti-interference mechanism and modular maintenance characteristics enable it to meet the needs of rapid diagnosis in clinical environments while reducing maintenance costs. Users must strictly follow the operating specifications to ensure long-term and stable operation of the equipment.

■ Functions
1. Data Input
The keypad board is an important component for users to interact with the ECG machine. It is equipped with a standard alphanumeric flexible keyboard, which can be used to enter the patient's basic information, such as name, age, gender, medical record number, etc. It can also set various parameters of the ECG machine, such as recording time, printing format, measurement parameters, etc.
2. Quick Operation
A dedicated "one-touch" button is provided to facilitate operators to quickly start common functions such as ECG acquisition, rhythm printing and ECG transmission. For example, in an emergency, a specific button can be used to quickly start collecting the patient's ECG data, or quickly print out the current ECG rhythm map, so that doctors can view it in time.
3. Menu Navigation
The arrow keys and confirmation keys on the keyboard can be used to easily browse and operate the menu system of the ECG machine, enter different functional modules, and select various settings and operations, such as entering the storage management module to view the saved ECG records, or entering the communication settings module to configure the network connection of the device.
4. Function control
The keyboard can be used to control various functional states of the electrocardiograph, such as turning the power on or off, pausing or continuing data collection, switching between different display modes, etc. In addition, there may also be some special function control buttons, such as heart rate alarm setting, lead selection, etc., to meet different clinical needs.

■ Working Principle
1. Circuit Architecture
Input Layer: The conductive contacts of the elastomer membrane keyboard contact the silver paste lines on the PCB to form a closed loop.
Signal Processing: The Application Specific Integrated Circuit (ASIC) de-jitters the key signal and transmits it to the mainboard via I²C or SPI protocol.
Output Control: Receives the mainboard feedback signal to drive the backlight LED or screen prompt (such as the "lead off" alarm).
2. Interface Design
Flexible Printed Circuit (FPC) Connection: Communicates with the mainboard via the ZIF (zero insertion force) connector, supporting plug-and-play.
Anti-interference mechanism: Through differential signal transmission and shielding layer design to reduce the impact of electromagnetic interference (EMI) on the signal.
