With the part number XNX-UTAV-RNCB1, the Honeywell gas detection transmitter features a catalytic bead sensor tailored for detecting combustible gases between 0 and 100% LEL. This device is designed to be highly efficient and is powered with an operating voltage of 16-32 Vdc, consuming just 6.5 Watts during operation. The transmitter is lightweight at 5 pounds and is built from painted LM25 aluminum, providing a durable marine-grade finish for resilience against corrosive environments.

Its operational capacity is broad, functioning effectively in temperatures ranging from -40°C up to 65°C, depending on the installed sensor. Additionally, it maintains performance in relative humidity levels from 20% to 90% RH without condensation. The XNX-UTAV-RNCB1 is rated with an IP66/NEMA 4X enclosure, ensuring it remains protected against dust and water exposure.

For output capabilities, the unit transmits HART communication over a 4-20 mA signal and includes three relay outputs—two for alarms and one for fault detection—delivering versatility in notifications. Each relay carries a rating of 250 VAC at 5A, or 24 VDC at 5A under resistive loads. There are four cable entries compatible with 3/4” NPT connections to facilitate installation. Users can monitor system performance through a clear backlit 2.5-inch LCD screen that features a high-resolution dot matrix display, making it easy to read at a glance. The XNX-UTAV-RNCB1 also comes with necessary approvals including UL/CSA certifications for use in Class I Division 1 areas and Groups B, C, and D, confirming its suitability for various industrial applications.
