ST-301 Temperature & Humidity Transmitter – 0–10 V / 2–10 V / 0–3 V Output

The ST-301 Temperature and Humidity Transmitter measures relative humidity and ambient temperature for environmental monitoring and climate control. With 0–10 V / 2–10 V / 0–3 V analogue voltage output, it is intended for integration with compatible PLCs, BMS systems and automation controllers.

Key features

• Combined temperature and humidity measurement: monitor both environmental parameters with one transmitter.
• Voltage output: 0–10 V / 2–10 V / 0–3 V. Check the required signal range against your receiving equipment.
• Wall-mounted design: suitable for fixed environmental monitoring installations.
• Screw terminal connection: for connection to compatible monitoring and control equipment.
