Smart switching relay with 2 circuits, capable of switching up to 2 separate phases, can be installed on the DIN rail of the electrical cabinet, with Wi-Fi, LAN and Bluetooth connection

Shelly's professional 2-circuit relay can communicate with Wi-Fi, wired network (LAN), and Bluetooth connection, and is a solution suitable for both home automation of apartments and professional automation of more serious commercial buildings (stores, condominiums, shops, etc.). The PRO product line is primarily intended by Shelly for the automation of newly constructed buildings, where building automation can be solved simply and professionally with Shelly Pro devices, without additional cabling, with relays placed next to the circuit breakers in the electrical cabinet.

Product features:

- LAN, Wi-Fi and Bluetooth support
- Simultaneous LAN and WiFi are supported
- Simple pairing with the Shelly Cloud app via Bluetooth
- It also has two switch inputs
- 2 outputs, each 16A max. performance, a total of max. With 25A performance
- Suitable for voltage-free switching, direct current and alternating current switching
- Its two independent circuits are suitable for switching even two separate phases
- DIN rail compatible

The product is a member of the Shelly PRO product range, which are equipped with:

- With an internal thermometer, which switches off the device in the event of possible overheating,
- With overvoltage protection, which cuts off the controlled circuit in case of overvoltage detection to protect electrical consumers,
- With maximum power protection, which switches off the controlled circuit if too much power is detected,
- And which are all made of fire-resistant and heat-resistant materials (V-O).

All PRO products:

- Supports HTTP/HTTPS webhooks so enhanced Shelly Pro products can easily connect, notify or control compatible products or other automation systems
- Timed off/on activations for sunrise/sunset times are supported,
- They can handle up to 50 timers (stored on the device, also working offline),
- Fully supports mjS scripts, allowing customers to create their own features and functions! Shelly Pro line devices allow the simultaneous execution of multiple scripts depending on different triggers such as input/output status, sensor data or WLAN requests

Product features:

- LAN, Wi-Fi and Bluetooth: It is capable of Wi-Fi and LAN connection at the same time, and pairing with the phone is easier than ever before, using a Bluetooth connection
- In the case of star-point wiring, it is also an ideal solution for the cost-effective automation of newly built apartments and commercial properties
- 2-circuit relay: with 2 independently controlled outputs, max. 16A, total max. It can switch 25A power.
- Voltage-free switching is also supported: the relay circuit is independent of the power supply provided for the operation of the relay, suitable for DC and AC switching, or even for voltage-free switching (dry contact)
- It can also be operated from a voltage between 110-240 V AC
- Wire cross-sections: switched circuit ("I" and "O"): 2.5mm2, the other inputs (feed for operation, switch inputs): 1.5mm2
- Super fast ESP32 processor: fast operation, fast notifications.
- Suitable for controlling many devices: Lighting, for automating household appliances, for controlling sprinkler systems, pool mechanics, for automating heating and many other devices. Devices requiring voltage-free switching are especially popular, e.g. boiler, door opener motor and motorized garage door.
- Increased safety: Made of fire-resistant (V-0) material, the device is equipped with overheating protection.
- Increased IT security: MQTT and WSS support, TLS and custom certificates are also supported.
- No hub / central unit required: Connect directly to the WiFi router to access the Internet and the factory cloud so that it can be controlled as simply as possible from the Shelly Cloud App.
- It can be integrated with almost everything: it can be controlled not only with cloud voice assistants (Alexa, Google Home), but also with many commercial and open source home automation systems.
