The Honeywell XNX-AMSI-NNNNN functions as a precise gas detection transmitter, capable of reliable detection in challenging industrial environments. Designed to operate under varying electrical conditions, it accepts a voltage between 18 and 32 VDC, with 24 VDC being the nominal level. At a weight of 11 lbs, this transmitter is built for stability and robustness.
Its enclosure is rated as IP66, conforming to NEMA 4X standards, providing extreme protection against environmental elements such as moisture and dust. The operational temperature range spans from -40°C to 65°C, ensuring performance across a wide spectrum of climates. In addition, this unit tolerates humidity levels between 0 and 99% RH, adding to its versatility for indoor and outdoor installations.
Power consumption reaches a maximum of 9.7 watts when connected to a Searchpoint Optima Plus and 13.2 watts for a Searchline Excel. The gas detection capabilities include an infrared sensor tailored for effective operation with both types of detectors, in addition to an option for a generic 4-20 mA input. The output signal is configured as a 4-20 mA signal with HART, allowing flexibility in system integration for monitoring and control purposes.
Accuracy plays a crucial role in gas detection, and this transmitter features a signal accuracy of ±1% of full scale, ensuring precise readings. The device incorporates five M25 cable entries to facilitate effective wiring configurations. There is no local HART interface included, but the transmitter supports mounting via integral lugs for surface installation or can be adapted for optional pipe or ceiling mounts. The XNX-AMSI-NNNNN lacks output or relay options, thus providing straightforward output via the 4-20mA/HART signals only.
