Contract Rating
1A/120VAC or 1A/24VDC
Configuration
SPST, Normally Open relay
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.
