SDC-HT(C)-MOD - Duct Mount

Smart humidity / temperature transmitter duct mount with modbus communication

Less Complexity, More Choice – Our Duct Sensor Just Got Smarter

• SDC‑HT‑MOD Humidity and temperature – pure Modbus RTU/ASCII. No analog outputs. Lower cost, less wiring, perfect for digital systems. 
• SDC‑HTC‑MOD Temperature, humidity, and CO₂ in one duct housing. Also Modbus‑only. One device, three critical parameters. Ideal for demand‑controlled ventilation and IAQ monitoring.

Going digital brings more than increased accuracy! Our sensors calculate a whole range of additional values directly on board.

• dew point
• enthalpy
• mixing ratio
• absolute humidity
• wet bulb temperature

All available right from the Modbus register. No post‑processing, no extra hardware.

Applications

• Climate measurements for data centers
• Humidity and temperature measurement for supply and return air ducts in heating, ventilation and various air conditioning applications
• Supervision of critical humidity and temperatures

Features

• Humidity, temperature and CO2 measurement for air ducts
• Sensor reconditioning function against contamination
• Anti-Creep function for high humidity environments
• Minimum and maximum temperature, humidity and CO2 memory
• Selectable averaging filter for the measurement signal
• Optional LCD display (OPC-S) or external display (OPA-S / OPU-S)
• Status LED
• Modbus RTU/ASCII RS485 for monitoring and configuration
• Copy of settings with accessory (AEC-PM2)
• Automatic device address increment when copying settings (AEC-PM2)
