Connect via pluggable, color-coded terminal blocks (12 to 28 AWG wire). Ensure you use only certified M25 cable glands to maintain the unit's explosion-proof rating.
Select the correct sensor technology (e.g., Catalytic, Electrochemical, or Infrared) and the target gas type. Xnx Universal Transmitter Quick Start Guide
The Honeywell XNX Universal Transmitter is a highly versatile industrial gas detection platform designed for use in hazardous areas worldwide. It supports multiple sensor technologies—including electrochemical, infrared, and catalytic bead—allowing it to detect a wide range of hazardous gases while offering flexible communication options like 4-20mA, HART, Modbus, and Foundation Fieldbus. The Story of a Smooth Installation
: Define standard operational trip points for Alarms 1 and 2. 6. Calibration Procedure The Honeywell XNX Universal Transmitter is a highly
The XNX is designed to work with various sensor technologies, including: For toxic gases and Oxygen. Catalytic Bead: For flammable gases (LEL). Infrared (IR): For combustible gases and CO2.
Wire the Alarm 1, Alarm 2, and Fault relays to the designated relay terminal block using normally open (NO) or normally closed (NC) configurations. Sensor Installation and Configuration Before handling the equipment
Verify that the transmitter's certification matches the hazardous area classification of the installation site (e.g., ATEX, IECEx, or UL/CSA).
Before handling the equipment, ensure all safety protocols are met.
