The Gas detector is designed for the detection of Oxygen O2 and provides 2 internal relay outputs for ventilation control and alarm, a 85dB Alarm buzzer and an LED alarm indicator. The Gas detector provides analogue (4-20mA and 0-10VDC) and digital (Modbus RTU) output signals. The supply of the gas detector is 24VDC or 230VAC with the optional available power supply. The light grey ABS plastic enclosure is IP 65 protected and the internal sensor can be easily replaced when its life time is over. The Gas detector operates also „standalone“, without any gas monitor. The Gas detector is also available with an incorporated dispay, a remote sensor probe, as a duct-mount version or in a neutral IP20 enclosure for Indoor-Installation.
