Aci A/RH5-AN-O Humidity Sensor 5pct

Product Description

The ACI A/RH5-AN-O relative humidity transmitters are designed for HVAC/BAS applications with a proportional 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output for 5% measurement. Features include on-board DIP switches for output signal selection and AC or DC power source compatibility. It is suitable for outdoor air monitoring, economizer control, and psychrometric calculations.

• Thermoset polymer capacitive sensing element with a factory-applied hygroscopic filter
• Proportional analog current or voltage output signal
• Integral DIP switches for field selection of the output signal and supply voltage

Product Highlights

The humidity transmitter utilizes a thermoset polymer capacitive sensing element with a factory-applied hygroscopic filter, enhancing resistance to moisture, dust, and chemicals, ensuring long-term reliability.
