Dahua DHI-ARM7012-W2 — 433MHz Wireless WallSwitch Relay Module
The Dahua DHI-ARM7012-W2 is a 433MHz wireless WallSwitch, a wireless wall switch relay module. Dahua describes it as a power switch that remotely controls 100-240 VAC power, so you can switch mains power remotely: output terminal N is connected directly to input terminal N, and the connection between output terminal L and input terminal L is controlled by opening and closing a built-in relay. It also measures power consumption, and has protection against overvoltage, overload and overheating. It is wired into mains power, so installation should be carried out by a competent person.
Also listed as ARM7012-W2.
Key features
- Frequency hopping and two-way communication keep the wireless link stable.
- Jamming detection and communication encryption (AES128).
- Monitors voltage, current and energy consumption.
- Overheat and overload protection, and protection against overvoltage.
- Relay output: 1 channel, NO or NC, 100-240 VAC, max 13A.
- Cloud update, with automatic restore if a cloud update fails.
- Test mode, and one indicator for pairing and communication status; wall mount.
