The XNX mA transmitter provides a simple and convenient way to set mA levels for your sensors. It comes with three relays: one for alarm level 2.3.3 Modbus 1, one for fault state, and a third for special states. The fault relay interface indicates which state is on the transmitter and allows the user to set up the fault relay. Honeywell Analytics recommends the fault relay interface.

XNX wireless gas detectors are an excellent choice for total integrated monitoring solutions. XNX transmitters can be equipped with a ceiling mount bracket kit (1226A0358), enabling easy installation and mounting of the devices in any location. These transmitters are compatible with different sensing technologies, which allow you to connect them locally or remotely to various devices and systems.
The programmable XNX universal transmitter is equipped with a user-friendly user interface. Its main screen displays the system’s status and provides options for configuration and monitoring. In addition, the transmitter has an Edit ID menu where you can make changes. For instance, you can change the length of the fieldbus path, enabling you to customize your XNX transmitter to operate efficiently.
The XNX transmitter comes with three types of sensors, depending on its model. The transmitter has three personality options based on the type of sensor. Choose from MV, EC toxic, oxygen, or IR sensors. Upon setting up your XNX transmitter, make sure it is calibrated. The manual also covers calibration. When it comes to gas detection, it is important to calibrate your transmitter regularly.
XNX xnx transmitter calibration
XNX Universal Transmitter has many features, including gas and radiation-inhibition calibration, 0 to 22 mA output range, force and warning, and overrange, low signal, and blocked beam output. This calibration is necessary to maintain functional safety, even under low-demand applications. XNX transmitters are available with a SIL-2 or SIL-3 capability.
A typical XNX transmitter has six data and eight registers. Besides the XCD gas sensor, it also features a 1200-day EOL and TB-3 Modbus 3-10 S communication interface. It also includes an LSB repeat of Modbus address. Using an XNX transmitter is easy – you just need to follow a few simple steps to ensure that your system is working as it should.
First, the transmitter must be properly configured for the gas it is monitoring. For example, if the XNX transmitter is used for EC/mV/IR gas measurement, it must have the proper mV/IR calibration. Alternatively, you can also configure the transmitter to perform bump testing for certain gases. Once you have the correct configuration, XNX transmitters are ready for use.
To ensure the integrity of your XNX Universal Transmitter, you should check its fault codes. If the transmitter displays an Optima or Excel fault code, it is not ready for calibration. If the XNX transmitter has been running for 24 hours without calibration, you must check its EEPROM (safety critical RAM block) or Excel signal level to make sure that there’s no malfunctioning system.
XNX xnx transmitter mA level settings
When you use the mA output of your telemetry system to control a device, you must adjust its mA level settings to match the value of the device. The mA level settings can be modified with the help of the Configuration Menu in the Main Menu. The XNX Technical Manual includes a table with the current values of the faults, warnings, and output currents.
The mA output screen on the XNX Universal Transmitter is displayed to provide you with information about the device. This screen shows gas data, transmitter information, and alarm settings. You can also change the range/alarm settings of the device. To do so, click the’mA Levels Menu’ and select a desired range.
The mA level settings on the XNX transmitter are controlled using three relays. The first relay is for the alarm level, while the other two are for the special states. The optional Modbus interface provides a way to configure all transmitter local states. A third relay is for the fault state. A fault relay interface is highly recommended. Once you have changed the mA level settings on your transmitter, you can reset the transmitter.
When using an ATEX sensor, you must follow the manufacturer’s instructions carefully. Make sure the transmitter is properly grounded, and earthed. Earthing is important for both intrinsic and electrical safety, and it limits radio frequency interference. If you use the XNX Transmitter for a gas monitor, be sure to install it properly in order to avoid electrical hazards and interference.
