Unlock a New Level of Smart Control and Automation
Integrate your existing low-current devices into the powerful Ajax ecosystem with the AJAX Wireless Smart Relay. This compact and versatile device is engineered for remote control, allowing you to switch appliances on and off with a single tap in the Ajax mobile app. From activating electric locks and gates to rebooting routers or controlling lighting, the Relay provides a seamless bridge between your security system and home automation.
Versatile and Powerful by Design
The AJAX Relay features a potential-free (dry) contact, which is not galvanically connected to the device's own power supply. This crucial feature allows it to be safely used in a wide variety of both low-voltage and household electrical networks, essentially mimicking a button or switch to control third-party equipment. Whether you need a continuous power state (bistable mode) or a short impulse for devices like electric strikes (pulse mode, with duration adjustable from 1 to 255 seconds), the Relay offers the flexibility to suit your needs.
Uncompromising Reliability and Safety
Operating on Ajax's proprietary Jeweller radio technology, the Relay ensures secure, encrypted, and long-range communication with the hub up to 1,000 meters away in open space. It's built with robust protection mechanisms, automatically shutting down in the event of a voltage surge, dip, or overheating to protect both the relay and the connected appliance. You can monitor the device's voltage level directly within the mobile app for complete peace of mind.
Compact and Easy to Install
Designed for convenience, the miniature housing (39x33x18 mm) allows the Relay to be easily installed inside a standard junction box, an electrical panel, or the housing of switching units. Connecting the Relay to your Ajax hub is a simple process that takes less than a minute—just scan the QR code with the app.
Key Features:
- Remote Control: Switch low-current devices on and off via the Ajax app from anywhere in the world.
- Dry Contact Relay: Galvanically isolated contacts allow for safe control of various electrical circuits.
- Flexible Operating Modes: Choose between bistable (on/off switch) and pulse (button press) modes.
- Automation Scenarios: Program actions in response to alarms, security mode changes, or schedules.
- Built-in Protection: Safeguarded against voltage surges (6.5V min, 36.5V max) and overheating (>65°C).
- Long-Range Communication: Jeweller radio technology provides stable two-way communication up to 1,000 meters from the hub.
- Compact Size: Easily fits into standard electrical junction and mounting boxes.
