Honeywell XNX-UTAV-NHNNN Universal Transmitter – Reliable Gas Detection for Demanding Industrial Environments

Technical Specifications

• Brand: Honeywell
• Model: XNX-UTAV-NHNNN
• Series: XNX Universal Transmitter
• Measurement Range: 0–100% LEL for combustible gases; 0–100 ppm for toxic gases (sensor dependent)
• Frequency Response: 0–10 Hz typical for electrochemical sensors; 0–20 Hz for catalytic bead sensors
• Sensitivity: 1% LEL for combustible sensors; 0.1 ppm for many toxic sensors
• Linearity: ±2% of full scale for most sensor types
• Resolution: 0.1% LEL or 0.1 ppm depending on the sensor and range
• Temperature Range: −40°C to +65°C (−40°F to +149°F) operating
• Environmental Tolerance: NEMA 4X / IP66 stainless steel housing; resists corrosion, dust, and water ingress
• Anti-Interference: EMI/RFI protection meets industrial EMC standards; shielded electronics reduce false alarms
• Output: 4–20 mA analog plus Modbus RTU digital communication
• Input Power: 24 VDC nominal (10–30 VDC range)
• Display: Backlit LCD with real-time gas concentration and status indicators
• Mounting: 2-inch pipe mount or wall mount; remote sensor option available
• Certification: ATEX, IECEx, UL, CSA, and INMETRO compliant versions available (specific approval depends on configuration)

Installation Guide

• Choose a mounting location where gas accumulation is likely and airflow is representative.
• Mount the transmitter vertically using a 2-inch pipe or a sturdy wall bracket.
• Keep the sensor inlet free from dirt, water, and direct spray from cleaning processes.
• Connect 24 VDC power using shielded cable to reduce electrical noise pickup.
• Route the 4–20 mA signal and Modbus wires separately from high-voltage lines.
• For remote sensor mounting, use Honeywell-approved cable and junction boxes only.
• After wiring, verify the zero and span readings with certified calibration gas.
• Set alarm relay thresholds according to your site safety procedures.
• Perform a full functional test before putting the transmitter into normal service.
