SPXCDALMO1 | Honeywell Sensepoint XCD Fixed Gas Detector
Reliable oxygen monitoring for hazardous areas. The Sensepoint XCD automatically recognizes sensor cartridges and delivers clear 4-20 mA signals. This industrial-grade detector combines ATEX/IECEx safety with easy configuration, making it a smart choice for plant safety.
Key Features at a Glance
- Oxygen Measurement: 0-25.0% v/v O₂ with automatic sensor recognition (mV, EC, or O₂ family).
- Output Signals: Normal 4-20 mA, fault < 1.0 mA, inhibit 2.0/17.4 mA, over-range 22.0 mA.
- Alarm Relays: Two independent alarm relays (lower and higher levels) and one fault relay – all de-energized, NO, non-latching.
- Inhibit & Timeout: Inhibit signal during setup (default 2.0 mA for O₂ or 17.4 mA); timeout disabled for operator control.
- Deadband: Built-in deadband prevents nuisance readings near zero.

Expert Review – Plant Manager’s Insight
“The Sensepoint XCD removes guesswork. Its auto-sensor recognition and clear fault/warning codes reduce downtime. We use it in chemical storage and boiler rooms – the deadband feature eliminates false alarms, and the Modbus integration fits our legacy PLCs perfectly.” – Site Reliability Engineer, 12+ years.
Typical Applications
- Chemical plants & refineries
- Wastewater treatment (oxygen deficiency)
- Confined space entry monitoring
- Pharmaceutical manufacturing
- Food & beverage cold storage
- Laboratory & research facilities
Frequently Asked Questions (FAQ)
- Which gases can this detector measure?
This model is for oxygen (O₂) only. Other Sensepoint XCD cartridges cover toxic and flammable gases.
- What does the fault relay do during a power loss?
The fault relay is energised normally and de-energises on fault, providing a fail-safe alarm.
- How do I clear a W-04 over-range warning?
Press the ✓ (tick) key after gas levels return to safe range.
- Is the sensor interchangeable in the field?
Yes. The transmitter auto-detects the new sensor type – no reconfiguration needed.
- What is the inhibit level for oxygen?
Default is 2.0 mA, but you can set it to 17.4 mA via the menu.
- Can I use this in a SIL-rated loop?
Yes, it meets SIL 2 (IEC 61508) when used with suitable safety systems.
- Why does the display show F-02?
Cell failure – replace the oxygen sensor cartridge.
- How to set the Modbus ID?
Navigate to Configuration > Modbus and adjust ID, baud, parity.
- Is a weather shield included?
Not standard, but available as an accessory for outdoor use.
- What is the warranty period?
12 months from date of purchase.
