Honeywell Sensepoint XCD Fixed Gas Detector

Product overview

The Honeywell Sensepoint XCD is a fixed gas detector suitable for industrial applications, capable of detecting flammable gases, toxic gases, and oxygen. It has a 3-wire 4-20mA output and RS485 MODBUS communication function. It is equipped with built-in alarm and fault relays, a local display screen, and can be fully configured through a non-invasive magnetic switch interface to protect personnel and factories from related gas hazards.
