Product Information Sheet
210-2000
Overview
CPC’s CO
2
sensor (P/N 210-2000) is a non-dispersive
infrared analyzer designed for measuring
environmental CO
2
concentration in ventilation
systems and indoor spaces. Its measurement range of
0-2000 or 0-5000 ppm covers the range required to
monitor compliance with ASHRAE and other
ventilation efficiency standards.
An LCD display is available to provide local indication
of CO
2
concentration and facilitate the setup and
calibration process. An adjustable setpoint relay is
available for direct control and alarm applications.
Microprocessor-based digital electronics and a
unique self-calibration algorithm improves long-term
stability and accuracy
Mounting
Before mounting, remove the door from the circuit
board by pressing a screwdriver against the locking
tab on the top of the enclosure. Pry the circuit board
away from the mounting plate using a screwdriver
inserted into the two tab slots on the top of the
enclosure.
Choose a location for the sensor with good air
circulation, away from ventilation inlets, doors,
windows, or other points where fresh air enters the
room. The sensor should be mounted at least 4-1/2
feet above the floor. The environment temperature
must be within 32°–112°F (0°–50°C).
If wiring will be coming in through the mounting
plate from the back, punch out openings in the
mounting plate and use the plate as a template for
locating holes. Mount the mounting plate against a
wall or other flat surface by using the two mounting
holes and the screws provided (use wall anchors for
drywall installations).
NOTE: Sensors must be mounted vertically (straight
up and down) to ensure proper readings.

Summary
Carbon Dioxide Sensor Product Information Sheet 210-2000 Wiring The mounting plate has two sets of three-terminal connectors. The connector on the left side of the mounting plate is where sensor power and the signal- to-I/O-board connection is made. The connector on the right side is where connectio...
Carbon Dioxide Sensor Product Information Sheet 210-2000 Setting the Volts/Amps Switch The front of the circuit board has a switch that controls whether the analog output sends a signal as voltage (V) or milliamps (mA). To work with CPC I/ O boards, this switch should be set to voltage (the DOWN pos...
Carbon Dioxide Sensor Product Information Sheet 210-2000 Span The Span parameter determines whether you want to measure concentrations between 0-2000 ppm or 0- 5000 ppm. If set to 2000 ppm, the sensor’s analog output signal will be scaled properly so that the highest output voltage corresponds to 20...
