DESCRIPTION
Model A/RH1 Relative Humidity Transmitters provide RH
readings at ±1% accuracy using a ceramic resistive sensor
offering a 20% to 90% operating range. The transmitters
come in wall, duct, and OSA mounting styles. They have
multiple field-selectable outputs, including 4-20 mA, 0-10V,
and 0-5V signals. The supply power is also selectable as 24
VDC or 24 VAC.
FEATURES
• Accuracy of ±1%
• Duct and OSA twist-off weatherproof housing
• 24 VDC or 24 VAC power (field-selectable)
• 4-20 mA, 0-10V, or 0-5V signal (field-selectable)
• Field-calibratable
• Optional temperature sensor
