The SPXCDALMO1 is a fixed industrial gas detector belonging to the Honeywell Sensepoint XCD family. This model monitors oxygen concentration across a 25.0% v/v range and suits continuous safety monitoring in process plants. Moreover, its ATEX/IECEx certification allows deployment in classified hazardous zones.
The part number itself encodes key build options. Specifically, SPXCD identifies the Sensepoint XCD platform, while the A denotes ATEX/IECEx/KTL/PA and GB certification. In addition, the L specifies an LM25 enclosure, the M indicates M20 cable entry, the O marks the oxygen sensor type, and the 1 confirms the fixed gas range.
The SPXCDALMO1 automatically recognizes its connected sensor cartridge by gas family, whether mV, EC, or O2 type. Its analog signal output follows a clear diagnostic scheme. For instance, a fault level reads ≥0.0 to <1.0 mA, and an inhibit state shows 2.0 mA or 4.0 mA (17.4 mA for oxygen). Meanwhile, normal measurement scales across 4.0 mA to 20.0 mA, and the maximum over-range status reaches 22.0 mA.
Alarm and fault relays are configurable. Alarm Relay 1 handles the lower alarm level, and Alarm Relay 2 manages the higher alarm level. Both relays are de-energized normally, close on alarm with a Normally Open contact, and run non-latching. Furthermore, the fault relay energizes normally and de-energizes on a detector fault below 1 mA.
Communication and identification features add flexibility. The Modbus interface defaults to ID 1, 19,200 baud, and EVEN parity. Besides, an optional location tag number supports unit identification, and a selectable temperature display toggles between °C and °F. The deadband function shows zero when readings fall inside a predefined range.
The SPXCDALMO1 ships in an LM25 enclosure with an M20 cable entry, matching ATEX and IECEx installation practice. Its rugged housing resists corrosion in chemical and petrochemical settings. Therefore, the detector performs reliably in outdoor and washdown-adjacent locations.
Operators should watch temperature limits closely. Specifically, warning W-02 triggers when transmitter temperature limits are exceeded, and the display clears once conditions normalize. Additionally, the unit weighs about 5 kg including packaging, so single-person handling remains straightforward.
Begin by confirming the hazardous area classification matches the ATEX/IECEx rating of the SPXCDALMO1. Next, route cabling through the M20 entry and secure the gland to maintain ingress protection. Moreover, mount the detector at a height suited to oxygen monitoring, since oxygen behaves differently from heavier gases.
After wiring, apply supply power and let the transmitter initialize. Then verify the 4-20 mA loop against a calibrated meter. Finally, configure alarm thresholds so the upper alarm stays within the user-defined scale, which prevents warning W-03.

Q: What gas does the SPXCDALMO1 measure?
A: It measures oxygen concentration over a 25.0% v/v range, using the O2 sensor option in the part number.
Q: What certification does this detector carry?
A: The "A" code confirms ATEX/IECEx/KTL/PA and GB certification for hazardous area use.
Q: What does warning W-01 mean?
A: W-01 signals that calibration is due, either because the interval elapsed or the sensor or gas type changed.
Q: How do I clear fault F-03?
A: Fault F-03 indicates significant zero drift, so re-zero or recalibrate the device to restore normal operation.
Q: What are the Modbus default settings?
A: Defaults are ID 1, 19,200 baud, and EVEN parity, configurable through the transmitter menu.
Q: How is the unit shipped?
A: Orders ship via Fedex, UPS, or DHL, with each detector packed in antistatic protection and a cardboard box.
