General
CD-200 and CD-200NL are Transmitter type
models of CO2 Sensor, which are for 0-20mA ,
4-20mA Current output module or 0-10V,2-
10V Voltage output module(Jumper select).
They are 4+ 2 wired (2 Power lines, 2 signal
lines and 2 relay lines) .

Relay Activated
On ≥ 1,000ppm,
Relay Deactivated
Off ≤900ppm
Relay on signal is designed to be activated
when CO2 measured value surpass 1,000ppm
and deactivated down to 900 ppm to avoid
unwanted rapid switching by hysteresis effect.
Relay activation and deactivation point could
be changed on sale as option.
