Specifications

Product Description

CDWN: Wall mount CO2 Transmitter optional with LCD or without LCD

CDWC: Wall mount CO2 Controller with LCD & keys

CDDN: Duct mount CO2 Transmitter

Applications & Features

CD-N series carbon dioxide transmitters/controllers are designed for monitoring & controlling indoor air quality
CDWN/CDWC is suitable for wall mount and CDDN is suitable for duct mount
High performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation
Stable, reliable and fast response
15 years sensor life without maintenance
Digital technology applied, over voltage and reverse polarity protection, high reliability and anti-interference capability
All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring(for CDWN/CDWC)
Multiple outputs selection, optional relay output to actuate the alarm or control function
LCD & function keys can set various parameters, calibrate and adjust output, so the product can be a stand alone controller(for CDWC)
