CO SENSOR E2617-CO - OPERATING PRICIPLE

Although several technologies are available for detecting CO, the most widely used and reliable approach today is electrochemical sensing technology.

Electrochemical principle: Inside an electrochemical CO sensor, electrodes are immersed in an electrolyte solution. When CO molecules enter the sensor, they react through an oxidation-reduction process at the electrodes, generating a small electrical current.

Signal processing: The magnitude of this electrical current is directly proportional to the CO concentration in the air. Internal circuitry then converts this current into standard output signals - typically 4-20 mA or Modbus - and sends it to a controller. Depending on the sensor type, it may activate built-in alarms (LED/buzzer) or trigger ventilation fans.

A key advantage of electrochemical CO sensors is their high sensitivity and accuracy across a wide range of concentrations, from 9 ppm and 25 ppm up to 1000 ppm or higher depending on the application.

CO SENSOR E2617-CO - PRACTICAL APPLICATIONS

CO sensors are widely used in areas prone to gas accumulation, especially enclosed or poorly ventilated environments. Typical applications include:

1. Basements and underground parking lots

This is the most common application for CO sensors. In parking basements of residential buildings, offices, or shopping centers, continuous vehicle movement generates significant CO emissions.

Sensors are installed on walls or ceilings to monitor real-time CO concentration.
When the measured value exceeds the preset threshold, the sensor triggers alarms or sends a signal to activate the ventilation system. This ensures airflow circulation and maintains safe air quality levels in compliance with regulatory standards.

2. Mining tunnels and industrial facilities

In industries such as chemicals, metallurgy, energy production, or any process involving fuel combustion, CO levels can rise significantly. In these environments, CO sensors with 4-20 mA or Modbus RTU outputs are typically integrated into automation systems to enable continuous monitoring, minimize the risk of CO poisoning, and ensure safe operation.

3. Smart buildings and automation systems

In modern smart building models, CO sensors equipped with RS-485 or Modbus communication are directly connected to the Building Management System (BMS). This allows real-time CO concentration data to be transmitted to the central control unit. The system can then automatically adjust ventilation fan operations, optimize energy usage, and enhance operational efficiency.

4. Other Applications

Beyond the environments mentioned above, CO sensors are also utilized in various locations that present a potential risk of toxic gas accumulation, such as:

- Large-scale automotive repair workshops

- Commercial or industrial kitchen ventilation systems

- High-capacity heating systems

- Fire stations

- Boiler rooms

- Warehouses

- Residential buildings

- Restaurants, hotels, and data centers

With their flexibility and high sensitivity, CO sensors have become indispensable components of modern air quality monitoring systems.

CO SENSOR E2617-CO - WIRING INSTRUCTIONS

To ensure stable and accurate operation, the E2617-CO CO gas detector must be wired according to industrial standards:

- Power supply: Provide 11-30 VDC to the +V and GND terminals on the device’s terminal block.

- Analog signal output: For 4-20 mA output (representing the measured CO concentration), connect OUT1 and GND to the analog input of the PLC, DCS, or central controller.

- Modbus RS485 Communication: For digital communication, connect the A and B lines to the RS485 bus. Ensure correct configuration of Modbus address, baud rate, and other communication parameters to guarantee proper integration with the control system.

- Technical documentation: Always refer to the wiring diagram in the official datasheet to ensure safe, compliant, and error-free installation.

The E2617-CO is widely used in underground parking garages, high-rise buildings, industrial facilities, and heavy-duty plants around the world. With advanced electrochemical sensing technology, a compact yet robust IP65-rated housing, high accuracy, and built-in alarm/ventilation control capability, the E2617-CO offers a reliable and efficient solution for protecting human health and meeting modern occupational safety standards.
