Automation Components Inc (ACI) A/RH2-20K-O Transmitter
The ACI A/RH2-20K-O is a high-performance outside air humidity transmitter designed for precise environmental monitoring in commercial HVACR systems. Utilizing a sophisticated capacitive sensing element, this Automation Components Inc device provides a highly accurate 2% relative humidity measurement combined with a 20K thermistor for temperature sensing. Engineered for versatility, it features field-selectable output signals (0-5 VDC, 0-10 VDC, or 4-20 mA) via internal DIP switches, allowing for seamless integration with diverse building automation systems. The rugged outdoor enclosure protects the electronics from harsh weather, while the single point field calibration capability ensures sustained accuracy over the life of the instrument. Whether managing building pressure or optimizing economizer cycles, the A/RH2-20K-O delivers the reliability required for critical climate control applications. These HVAC sensors support both AC and DC power configurations, providing installers with maximum flexibility during deployment.
Key Benefits
- Dual-Sensing Functionality: Integration of a 2% accuracy RH sensor and a 20K ohm NTC thermistor reduces installation costs.
- Universal Compatibility: Field-selectable outputs ensure the device works with almost any controller or PLC.
- Simplified Maintenance: On-board increment and decrement DIP switches allow for easy field calibration without specialized equipment.
- All-Weather Reliability: Specifically designed as an outside air humidity transmitter to withstand ambient environmental fluctuations.
- Flexible Powering: Compatible with various power sources for easier integration into existing electrical layouts.
Common Questions
How do I change the signal output on the A/RH2-20K-O?
The output signal (4-20mA, 0-5V, or 0-10V) can be adjusted using the internal DIP switches located on the circuit board.
Can this sensor be calibrated after installation?
Yes, the unit supports single-point field calibration using the on-board switches to maintain high precision over time.
Is the temperature sensor compatible with my BAS?
The 20K thermistor is a common standard, but always verify that your specific controller recognizes a 20K ohm resistive temperature curve.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
