The Honeywell SPXCDULNO1M serves as a reliable gas detector/transmitter within the Sensepoint XCD series. With a voltage rating of 16-32 VDC, this unit typically uses 24 VDC for its operations. Weighing in at 4.4 lbs, it is built to withstand demanding conditions, evidenced by its temperature operating range of -40 °C up to 65 °C.
The housing construction consists of aluminum, providing durability and protection. Furthermore, the device meets an IP66 rating, ensuring that it is both dust-tight and resistant to water ingress. Power consumption is capped at 3.7 W, enabling efficient operation.
For data communication, it employs the RS-485 Modbus protocol, facilitating integration with existing systems. The device is equipped with three relays, which include two for alarm conditions and one for indicating faults. It detects oxygen (O2) levels within the range of 0-25% by volume using Surecell electrochemical technology, making it highly effective for monitoring purposes.
The cable and conduit entry for the SPXCDULNO1M uses a 3/4 inch NPT size to meet installation requirements. Additionally, it holds UL/CSA certification for use in hazardous locations, confirming its explosion-proof capabilities. This combination of features allows the SPXCDULNO1M to perform reliably in various industrial applications where gas detection is critical.
