AT-EG01 CO Gas Detector is designed for fixed carbon monoxide gas monitoring applications. According to the product manual, the detector can be configured with a corresponding sensor module based on the selected target gas. Target gas, detection range and alarm setpoints are specified on the product nameplate.
The detector provides real-time gas concentration display and alarm status indication. It supports 4-20mA analog output, RS485 Modbus RTU communication and passive relay output for connection to gas alarm control panels, PLC systems or external alarm devices.
With die-cast aluminum housing, Ex d IIC T6 explosion-proof rating, IP66 protection and DC24V power supply, AT-EG01 CO Gas Detector is suitable for industrial carbon monoxide monitoring and gas safety system integration.

Relay output mode can be configured as standard or pulse mode.
The detector must be installed where gas leakage or gas accumulation is likely to occur.
The optimal mounting position should be determined according to the density of the target gas relative to air and the actual site risk. The sensor element should face downward.
General installation notes:
Avoid strong impact, vibration and strong electromagnetic interference.
Ensure easy access for maintenance and calibration.
Keep a minimum 0.5 m clearance from surrounding pipes and equipment.
Route the cable through the cable gland.
A sealing operation with 2 cm of epoxy resin potting compound is required at the wiring port.
Do not open the cover when energized.
Use proper grounding.
