AJAX Relay Jeweller
Control compatible electrical equipment remotely with the AJAX Relay Jeweller Wireless Dry Contact Relay. Featuring secure Jeweller communication, potential-free contacts, pulse and bistable modes, and a wireless range of up to 1,000 metres in open space, it is ideal for compatible gates, electric locks, valves, and smart automation projects.
Key benefits: Compact design, remote control, flexible switching, and integration with compatible AJAX security systems.
AJAX Relay Jeweller – Wireless Smart Relay for Remote Control & Automation
Smarter Control for Your Home and Business
The AJAX Relay Jeweller adds practical automation to your Ajax security system. Remotely control compatible electrical equipment to manage access, automate routines, and boost convenience.
Whether you’re upgrading a home installation or managing a commercial property, this compact relay offers flexible control through the Ajax ecosystem.
Control Compatible Equipment Remotely
Switch suitable electrical circuits on or off through the Ajax app or automation scenarios. Depending on the equipment and installation, you can control:
- Electric locks and access-control circuits
- Automatic gates and barriers
- Water shut-off valves
- Lighting circuits
- Irrigation systems
- Other compatible electrical control inputs
The relay does not power connected equipment. It switches the circuit through dry contacts, so the controlled device needs its own power source.
Flexible Switching Options
- Pulse mode — activates the relay for a set duration, ideal for equipment that responds to a momentary button press
- Bistable mode — changes the contact state and holds it until the next command
You can also configure the normal contact state to suit your application.
Reliable Wireless Communication
- Jeweller technology — connects to compatible Ajax hubs and range extenders
- Up to 1,000m range in open space (actual range depends on building layout, location, and radio interference)
- Encrypted communication — helps protect transmitted data
- Remote testing — simplifies system maintenance
Compact, Discreet Design
At approximately 39 × 33 × 18mm, the relay fits inside a suitable junction box or electrical enclosure — ideal where space is limited. An optional compatible DIN Holder supports DIN-rail mounting.
Built-in Electrical Protection
Voltage and temperature protection safeguard the relay when it exceeds specified operating limits.
Installation note: This is an electrical switching device, not a standalone smart plug. A qualified electrician or trained security-system installer must install it. Always verify the connected load, circuit voltage, and regional product specification first.
