The Honeywell 2108N4110N, part of the Searchpoint Optima Plus series, functions as a fixed gas detector (transmitter). Designed specifically for methane detection, this device operates within a voltage range of 24 VDC nominal, allowing for flexible application in different systems. With an impressive weight of 4.4 lbs, the 2108N4110N is built to withstand tough environments, as indicated by its IP66 enclosure rating.

The operating temperature spans an impressive range from -40°C to +65°C, making this detector suitable for various external and internal conditions. It features an infrared (IR) sensor with detection capabilities for methane concentrations from 0-100% LEL. The inrush current rating reaches a maximum of 800 mA at 24VDC, complemented by a power consumption rate of 3.7W when utilizing the infrared sensor.

For signal output, users can expect a 4-20 mA sink/source output along with an RS-485 Modbus RTU option, facilitating easy integration into existing monitoring systems. Relay outputs are also provided, with three terminals rated at 5A at 250 VAC that can be selected as normally open (NO) or normally closed (NC).

Constructed from epoxy-painted aluminum alloy (LM25), the enclosure offers durability and robust protection for the internal components. Conduit entry is made feasible through two openings of 3/4" NPT, enhancing installation options. Additionally, the detector boasts a response time (T90) of less than 30 seconds for methane, ensuring prompt detection in critical scenarios.
