Ajax Relay (Relay Jeweller) is a compact wireless dry‑contact relay module that allows an Ajax hub to control electrical equipment remotely. Suitable for installation inside a junction box, appliance enclosure or electrical panel, the Relay provides galvanically isolated contacts so you can safely switch low‑voltage control inputs or household control circuits (e.g., electric locks, gates, pumps, valve controls, router reboots or lighting control inputs).

• Potential‑free (dry) relay contacts — electrically isolated from the device power supply.
• Power supply: 7–24 V DC (recommended 12 V or 24 V). Reports supply voltage and includes over‑voltage protection.
• Operation modes: Bistable (on/off) and Pulse (0.5–255 s adjustable).
• Load capability: up to 5 A (to ~36 V DC) or up to 13 A at 230 V AC — follow local wiring regulations and use a qualified electrician for mains switching.
• Communications: Jeweller two‑way encrypted RF protocol; adjustable polling (12–300 s) and up to ~1,000 m open‑space range (region dependent).
• Small form factor for enclosure or DIN mounting; includes anti‑sabotage protection and temperature shutdown.

Why choose this Relay? It lets installers and integrators add remote control and automation to Ajax systems without hardwiring control circuits into the hub. The galvanically isolated contacts make it suitable for interfacing with control inputs on locks, gates, pumps and many appliances while minimising electrical interaction between circuits.

Installation & safety: Intended for installation inside an enclosure (IP20). Do not expose to weather; only mount in appropriate electrical enclosures. When switching mains voltages, observe local wiring regulations — mains wiring should be carried out by a qualified electrician. Check local compliance marks (CE/UKCA) and applicable installation standards before commissioning.

Notes: Product specifications and regional RF bands vary by market. Refer to the official Ajax Relay user manual for full installation, wiring diagrams and regulatory markings.
