Honeywell XNX Relay

The Honeywell Analytics XNX Universal Transmitter is a versatile platform that brings common wiring, displays and protocols to a wide range of gas sensors—ideal for upgrades, mixed-sensor plants, and standardized maintenance. Choose from electrochemical (EC) for toxic/O₂, infrared (IR) for hydrocarbons/CO₂, or catalytic bead for LEL monitoring. A large local display and magnetic-key menu simplify setup in classified areas.

Selection quick tips

Gas & sensor: pick EC / IR / catalytic by target gas and environment.

I/O & protocols: standard 4–20 mA (sink/source); add HART or Modbus RTU for diagnostics/SCADA.

Relays: optional 3× SPDT for local alarms/shutdown.

Enclosure: aluminum (cost-effective) or 316L stainless (corrosive/ offshore).

Approvals: choose ATEX/IECEx/UL-cUL variants to match your region and area classification.

Compatibility: XNX interfaces with Honeywell point/open-path sensors（model-dependent），enabling mixed fleets on one platform.

Price & availability (what drives cost)
Sensor technology, enclosure material, protocol/relay options, and regional approvals determine price and lead time. Tell us the gas, range, protocol, and enclosure—we’ll quote common configurations fast.

Manuals & datasheets
We provide install, wiring and calibration documents (quick links on request). Typical guidance covers mounting height, flow/ventilation considerations, and bump-test/calibration intervals.
