H5024 CO2浓度变送器,带继电器输出

CO2变送器，带2路继电器输出

CO₂ sensors with relay or serial output (RS485/RS232) are designed for industrial environments as well as spaces where the sensor’s appearance matters.

Selected models feature two relay outputs for alarm indication or control of external devices. Each relay can be assigned to a measured or calculated value, with configurable threshold, delay, hysteresis, and acoustic alarm. Controllers are equipped with a power relay (50 V / 2 A).
