Product Description:

YJJ MCX-MPCB1 Main Circuit-Board for Portable Multi-gas Detector Spare-Parts

Features:

I. Basic Introduction
MCXL-MPCB1 is the original factory replacement main circuit board assembly for the GasAlertMicroClip-XL (MCXL) four-in-one portable gas detector. The original factory accessory kit includes the mainboard, built-in lithium battery, and a complete set of fixing screws. It is available in a battery-equipped version and a standalone mainboard version without battery.
II. Hardware Core Parameters
Adapter: MicroClip-XL four-in-one detector (model MCXL-XWHM-Y-CN)
Sensor slots: 4 independent sensor bases, capable of accommodating O2, CO, H2S, and LEL combustible gas probes
Main control chip: Industrial-grade MCU, responsible for collecting weak current signals from electrochemical and catalytic combustion sensors, signal amplification, AD conversion, and concentration calculation
Power supply module: Equipped with the original built-in lithium battery; the entire device can operate for 18 hours when fully charged, and the charging time is ≤ 6 hours
External interfaces: Display cable interface, buzzer, vibration alarm component, infrared calibration communication interface, charging seat contacts
Operating environment: -20°C ~ +50°C; humidity 10-95% RH (no condensation)
Explosion-proof standard: The mainboard and entire device meet Ex ia IIC T4 safety explosion-proof, and the adapter meets IP66/IP67 waterproof and dustproof specifications
Circuit board origin: Manufactured by the original factory in Mexico
III. Built-in Functions of the Mainboard
Storage of sensor zero point and calibration data; automatic sensor, battery, and alarm hardware detection upon startup
Real-time calculation of 4 gas concentrations, driving the LCD screen to display values
TWA time-weighted average value, STEL short-term exposure peak value, and over-limit alarm logic operation
Three alarm outputs: 95dB buzzer sound, LED flashing, motor vibration alarm
Detector fault record, gas detection history data storage, infrared port calibration communication
Low voltage reminder, sensor aging fault identification
IV. Main Applications
1. Maintenance spare parts purpose
As a core replacement component for the MicroClip-XL four-in-one detector, when the mainboard is burned out, the circuit is faulty, the signal is abnormal, the calibration is impossible, or the detector fails to start, it can be directly replaced as a whole without separately repairing individual components, making the maintenance convenient.
2. Signal acquisition main control function
Receiving weak electrical signals from 4 gas sensors, processing the real-time concentrations of hydrogen sulfide, carbon monoxide, oxygen, and catalytic combustion combustible gas probes, serving as the brain of the entire device.
V. Sensor Specifications Adapted
H2S Sulfur Dioxide (0-100ppm), CO Carbon Monoxide (0-500ppm), O2 Oxygen (0-30% VOL), LEL Catalytic Combustion Combustible Gas Probe
