SKU: ERANNTEX Online Single Gas Detection Alarm
The Eranntex GTYQ-MIC-300 Online single gas detection alarm features a built-in three-wire 4-20mA output, making network monitoring a breeze. It connects directly to a standard RS485 bus. It also comes with two relay switches (switching outputs) that can directly control the device's start and stop when needed. If you require a voltage signal output, that's also an option. Connecting it to a computer is particularly convenient. After installing the accompanying host computer software, you can view real-time data from the field probes from your office, clearly showing concentration changes. All data can be stored on your computer for trend analysis or printed reports. It also has a clever feature that automatically tracks the zero point to prevent drift, making measurements more accurate and stable, eliminating the need to worry about deviations over time. Of course, if you require specialized customization, the manufacturer fully supports OEM or ODM services, allowing you to customize it to your needs.

|
Signal Output |
RS485 bus (RTU), three- or four-wire, 4-20mA, optional: 0-20mA, 1-5V, 0-5V, 0-10V. |
||||
|
Operating Environment |
Ambient temperature: -20°C to +55°C (typical), -40°C to +70°C (maximum). |
||||
|
Operating Voltage |
(Preconditioning system optional for higher temperatures and humidity requirements). |
||||
|
Power Reference |
12-36VDC. The standard power supply for a single device is a 24V, 1A or greater DC regulated switching power supply. |
||||
|
Operating Mode |
A 24V, 2.1A switching power supply can power 40 toxic gas detectors or 15 flammable and infrared gas detectors. |
||||
|
Mounting Method |
Fixed installation, online detection, diffusion measurement; available in pipeline, flow-through, and pump-type measurement. |
||||
|
Alarm Mode |
Pipeline and wall-mount versions. The operating pressure for pipeline versions is±30% of atmospheric pressure; pressure reduction is required if the range is exceeded. |
||||
|
Connecting Cable |
Default: 1 output, 2 optional passive contact (dry contact) outputs. Three alarm levels with configurable alarm points. Optional on-site audible and visual alarm. For 4-20mA, use a three-core shielded cable. For RS485, use a four-core shielded cable. For distances exceeding 1000 meters, the single wire diameter should be≥1.5mm; the shield should be grounded. |
