COMET T0418 Indoor Temperature Transmitter RS485

COMET T0418 Indoor Temperature Transmitter RS485

The COMET T0418 is an elegant, high‑precision indoor temperature transmitter designed for modern building automation, HVAC systems, and energy‑efficient climate control. Its slim, discreet light grey design fits perfectly into standard KU68 flush‑mount boxes – just like a light switch or thermostat – making it ideal for offices, schools, hotels, hospitals, conference rooms, or residential buildings.

The internal high‑precision sensor measures room temperature from –10 to +50 °C with an accuracy of ±0.5 °C and 0.1 °C resolution. The RS485 interface with Modbus RTU protocol (factory preset) allows seamless integration into any building automation, BMS, SCADA, or smart home system. Alternatively, ARION and Advantech ADAM protocols are supported.

Installation is quick and easy: simply clip it onto the existing wall box, connect power and RS485 – done. No drilling, no chiseling, and no visible housing. Thanks to its ultra‑flat form, the sensor extends only about 10 mm from the wall.

Despite its affordable price, you get full COMET quality – durable, maintenance‑free, with 3 years of warranty and outstanding long‑term stability through computer‑controlled manufacturing.
