Galvanically isolated DIN rail add-on for Shelly Pro devices for connecting DS18B20 and DHT22 sensors, 0–10 V analog, ±15 V digital, and potential-free contacts for monitoring and automation in residential and industrial applications. The Shelly Pro Sensor add-on is not a standalone device and must be connected to a compatible Shelly Pro device for power supply and operation. Compatible devices: Shelly PRO 1/2, Shelly PRO 1PM/2PM, Shelly PRO Dimmer 1PM/2PM, Shelly PRO EM-50, Shelly PRO 3EM, Shelly PRO Dimmer 0/1–10V PM. The Pro host device requires firmware version 2.0 to operate the PRO Sensor add-on. -Sensor connection expansion: Adds multiple sensor interfaces to Shelly Pro devices for versatile monitoring -Galvanic isolation: Safe and reliable operation through electrical isolation of the inputs -1-Wire interfaces: Each supports up to five DS18B20 sensors -Analog inputs: Includes two 0–10 V analog inputs, suitable for CO2, light, or pressure sensors -Digital inputs: Features two digital inputs to support signals from motion detectors, leak sensors, or switches -Potential-free solid-state relay output -Arduino sensor compatibility: Compatibility with most Arduino sensors enables custom automation projects -DIN rail mounting: Easy and secure installation on the DIN rail in private, commercial, and industrial control cabinets -Low power consumption: Consumes less than 0.5 W without connected sensors, thereby promoting energy efficiency -Configurable input settings: Enables logic inversion and adjustable thresholds for digital and analog inputs for flexible use Common applications: -Sensor monitoring and control -Climate optimization -Irrigation and outdoor management -Custom sensor projects
