Schneider SHO2XA2A Outdoor Temp/Humidity Sensor Analog

Product Overview

The SpaceLogic SHO2XA2A is an advanced outdoor air temperature and relative humidity transmitter designed for meteorological sensing and fresh air intake monitoring of Air Handling Units (AHUs). Enclosed in a highly weather-resistant housing, the device features a 2% accuracy thin-film capacitive RH sensor and an active temperature transmitter, shielded by an integrated solar radiation shield (Sun Shield).

The shield prevents direct sunlight, heavy precipitation, and thermal radiation from skewing sensor accuracy, providing reliable outdoor meteorological data for BMS free-cooling algorithms and HVAC enthalpy calculations.

Technical Specifications

Protocol / Communication	None. Pure analog hardwired transmitter.
I/O Points & Signals	Dual independent analog hardware outputs. Configuration selectable via DIP switches: Current mode 4 to 20 mA (maximum loop resistance 500Ω) or voltage mode 0 to 5 VDC / 0 to 10 VDC (minimum load resistance 10kΩ).
Power Supply / Voltage	24 VAC ±15% (50/60 Hz) or 12 to 30 VDC, with polarity reversal protection.
Sensor Parameters & Accuracy	Humidity Sensing: Thin-film capacitive relative humidity element Range: 0 to 100% RH Accuracy: ±2.0% RH over the critical 10% to 90% RH meteorological range Temperature Sensing: Active semiconductor transmitter Calibration range: -40 to 60°C (-40 to 140°F) Accuracy: ±0.3°C (±0.54°F)
Regulatory & Certifications	CE, FCC Part 15 Class B, RCM, RoHS, WEEE, NEMA 3R / IP65 weathering certification.
Enclosure & Material	UV-stabilized, impact-resistant polymer shield housing. Designed to prevent solar-heat gain while allowing free air flow across the sensor elements.

Typical Applications

BMS Enthalpy Control: Monitors outdoor air humidity and temperature to calculate real-time enthalpy. The BAS uses this to control outside air dampers, switching to free-cooling when outdoor air is more favorable than recirculated air.
Night Purge & Free Cooling: Feeds baseline meteorological data to the BMS, allowing automatic night purging to cool down building concrete slabs naturally during summer.
Winter Freeze Protection: Tracks sub-zero outdoor conditions in cold climates to preemptively modulate AHU heating coils, protecting water loops from freezing.
