Relay For ZG106 | Air Quality Sensors – Protronix

Relay for connecting to the ZG106 CO2 monitor. Relay closes when the limit concentration of CO2 is exceeded. CO2 concentration limit is set on the ZG106 CO2 monitor in ALARM mode. To avoid fast switching of the relay, when measured concentration level is near to the set level, hysteresis of 50ppm is automatically added.
