XNX-UTAI-NHNNN
Explosion-Proof Universal Transmitter

Honeywell Analytics · XNX Series · HART over 4-20 mA · Painted Aluminium · for Optima Plus & Excel

Description

XNX-UTAI-NHNNN is an explosion-proof universal transmitter. Honeywell designed it for harsh industrial environments. This device delivers reliable gas detection with HART communication. It supports 4-20 mA analog output and local HART interface port. The unit is pre-configured for Searchline Excel and Optima Plus detectors.

Housing uses painted marine-grade LM25 aluminium alloy. It withstands dust and moisture (IP66). The transmitter operates from -40°C to +65°C. It also handles 0–99% RH non-condensing. Five 3/4″ NPT conduit entries simplify wiring. This model does not include relay output — it focuses on precise gas monitoring.

Power consumption reaches 13.2 W maximum (with Searchline Excel receiver). Voltage range is 18–32 VDC. The local IS HART port allows easy configuration. This transmitter suits open-path IR gas detection systems. It ensures robust performance for leak detection and safety applications.

Technical Specifications
