CD-P1000-00-00U Johnson Controls Transmitter

Overview

The Johnson Controls CD-P1000-00-00U is a duct-mount carbon dioxide (CO2) transmitter engineered for HVAC and building automation systems. It features a high-accuracy, dual-channel nondispersive infrared (NDIR) sensor designed to monitor CO2 levels in ventilation air streams, facilitating demand-controlled ventilation (DCV) and ensuring optimal indoor air quality (IAQ).

Features

• High-accuracy dual-channel NDIR CO2 sensor provides long-term stability and resistance to pollution.
• Adjustable duct probe depth enables optimal placement of the sensing tip within the ductwork.
• Field-selectable output signals offer versatile compatibility with building automation systems.
• Robust construction with a low-profile polycarbonate enclosure and a gasketed, hinged cover.
• Supports energy-saving demand-controlled ventilation strategies, potentially reducing energy costs.
