XNX Universal Transmitter 2022


XNX Universal Transmitter

The XNX Universal Transmitter is a wireless device with two different types of output. The primary output is a 4-20 mA signal which refreshes every two seconds, and is proportional to the gas concentration. The transmitter can be isolated or connected to a source by a 4-Wire cable. The UT also features a 20mA current loop output which provides an analog indication of special states. This output is proportional to the gas concentration and is used for over-range indication. It overrides warning state if it occurs, but always overrides the alarm state.


The XNX universal transmitter offers a variety of options for controlling its internal circuitry. Its configuration menu can be accessed via the front panel. The configuration menu displays functions for each module, including baud rates and address settings. In addition, it also allows for the configuration of Level 1 and Level 2 security passcodes.

The XNX universal transmitter supports several standard communication protocols. It supports HART over 4-20 mA, Foundation Fieldbus, and Modbus. It is registered with the HART Communication Foundation and has been certified to meet U.S. and Brazilian standards. It also supports relay communication. The XNX-BT and XNX-UT are INMETRO-approved and UL-certified.

The XNX universal transmitter provides easy-to-use and low-maintenance solutions for gas detection and monitoring. It works with industry-standard PLCs and gas detectors and is designed to integrate with third-party gas monitoring controllers. It also has a wide variety of other features to accommodate various applications.

The XNX universal transmitter is compatible with multiple sensor technologies and personality options. Its pluggable terminal blocks allow for the connection of different sensors and applications. It also includes a Personality circuit board, which determines how the XNX transmitter should behave depending on the type of sensor attached to it.

The XNX transmitter supports eight different languages. Each language displays a different screen. It will show the current date in three different languages. You can change the date and time using the Set Date selection. The XNX transmitter also allows you to set the target gas. It also displays the warning code for gas.


The XNX-BT**.***** universal transmitter is equipped with the HART over 4-20 mA communication standard and supports relay communication, Modbus, Foundation Fieldbus, and CAN bus. It has been registered with the HART Communication Foundation and meets Brazilian and U.S. safety standards. This product is also INMETRO-certified for U.S. applications and is listed in the International Directory of Industrial Automation Products (INDICAT).

The XNX transmitter supports eight different languages. Each language has a different interface. A menu is provided to help you select the correct language for the user interface. The device also has settings for Zero and Span calibration and functional gas testing. However, the XNX transmitter is not suitable for use in oxygen-enriched environments. It should also be used by qualified personnel.

This universal transmitter comes with a comprehensive parts list. The main components include the transmitter case, the power supply, and the connectors. You can configure the transmitter’s operation modes according to your requirements. For example, you can configure the transmitter to operate in Source mode or Sink mode, or to enable the device to communicate with an external device.

The XNX transmitter is compatible with a variety of sensors. The XNX transmitter interfaces with devices from Sensepoint, HA Multi-Purpose Detector, and 705 field-proven line of devices.


The XNX-UT**.***** universal transmitter is capable of connecting to a bus of devices, such as PLCs and controllers. The transmitter can be configured via its front panel menus. The Configure Menu lets users set the Modbus address and baud rate. They can also configure the fieldbus options.

The XNX transmitter has three basic installation types. The first installation method involves using a single transmitter. A second installation option involves connecting multiple transmitters to a single power source. If more transmitters are installed, a larger power source is needed. XNX transmitters share a nominal voltage of 24V.

Depending on the configuration of the transmitter, there are several options available. For example, it is possible to choose the number of alarms to be sent. Moreover, the alarms can be set to either be automatically reset when the condition dissipates or remain active until manually reset. Additionally, the transmitters are compatible with a variety of sensors. Some of them include Foundation Fieldbus and HART/Modbus sensors.

The XNX transmitters come with three relays: one for alarm levels one and two, and a third for faults and special states. Using a fault relay in a facility is recommended by Honeywell Analytics, but this option is not mandatory. In the event of a power failure, the fault relay will open. Alternatively, users can configure the transmitter with a Modbus interface.
