4020301 - Humidity/temperature sensor

CRH-RW-24V Humidity and temperature sensor.
CRH is used for controlling the air humidity and temperature of indoor environments.
Can be used together with HERU and SAU to control humidity.

  • Humidity sensor 0-100% RH
  • Temperature sensor 0-50°C
  • Extremely low power consumption
  • 24V AC/DC supply
  • 2 x 0-10V DC outputs
CRH has a factory calibrated CMOS humidity and temperature sensor element with I2C communication. It has high accuracy and excellent long-term stability. CRH has extremely low power consumption which results in very low internal heating, which is a prerequisite for high measurement accuracy of relative humidity.
