Automation Components Inc (ACI) CO-R-RB-D Co Sensor W/Lcd Relay&Buzzer

The Automation Components Inc CO-R-RB-D is a carbon monoxide sensor developed to be used in various HVAC systems and other applications requiring CO detection. The device features an LCD screen that indicates current CO levels, and it also has integrated switches and a buzzer that triggers an alarm when CO concentrations exceed certain thresholds. When CO gas is detected, the sensor engages the relays, which can be implemented to do different things such as shutting off HVAC equipment, enabling ventilation systems, or activating alarms. The encased buzzer provides an auditory warning signal alongside the LCD's visual confirmation. This product is commonly used in an array of HVAC applications, notably furnaces, boilers, and water heaters.
