Crafted by Honeywell, the SPXCDULNFXM is classified as a flammable gas detector adept at operating on voltage between 12 to 32 VDC, with a standard nominal of 24 VDC. It is robustly designed, weighing 4.4 lbs, and constructed from epoxy painted LM25 aluminum alloy, ensuring protection in industrial environments.
This gas detector boasts an IP66 rating, which guarantees extensive protection against environmental elements, making it suitable for outdoor installations. Its operational temperature range spans from a frigid -40°C to a scorching 65°C, assuring reliability in extreme conditions. When it comes to storage, the SPXCDULNFXM continues to function effectively in temperatures from -25°C to 65°C.
In terms of humidity tolerance, it is capable of operating in continuous conditions of 20-90% RH and can briefly accommodate up to 99% RH without condensation. Powering the device requires a maximum consumption of 4.9 watts, particularly when using the catalytic sensor.
The output signal from the SPXCDULNFXM can be tailored as 4-20 mA, selectable between sink or source configurations, along with RS485 Modbus RTU capability for integration into larger systems. Notably, the unit features a maximum inrush current of 800 mA at 24 VDC, with relay ratings suited for three connections at 5A (250VAC), including two alarms plus one fault using a single-pole double-throw (SPDT) configuration.
Cable entry is facilitated by two 3/4 inch NPT openings. Additionally, the flammable gas sensor utilizes a catalytic bead type, specifically sensitive to methane concentrations spanning from 0-100% LEL. The mounting setup is versatile, offering an integral mounting plate with four M8 bolt holes or an optional pipe mount kit for adaptable installations.
