Ajax Relay

Relay Jeweller: turn any switch, lock, or shutter into part of the security system

A wireless relay small enough to fit inside a junction box, electrical panel, or DIN-rail enclosure (39x33x18 mm, 25 g), that puts a dry contact under remote and automated control. Because the contact isn't galvanically tied to the device's own power, it works safely in both low-voltage and household circuits, locks, roller shutters, water valves, gates, or a smoke cannon triggered by an alarm.

Two operating modes cover most use cases: bistable for on and off control, and pulse, adjustable from 0.5 to 255 seconds, for a momentary trigger like a gate release. Contact ratings depend on the load: up to 5 A at 24 V DC or 13 A at 110 to 230 V AC on a resistive load, dropping to 3 A and 8 A respectively on inductive or capacitive loads. Thermal protection opens the contacts if the mounting location exceeds 65°C or the device's internals reach 85°C.

Pairing takes under a minute, scan the QR code in the app, and a flexible external antenna keeps the radio link stable inside metal enclosures. Note that this is not a battery device: it needs an external 7 to 24 V DC supply, with 12 V or 24 V recommended.

• Bistable and pulse (0.5 to 255 s) operating modes
• Resistive load 5 A at 24 V DC / 13 A at 110 to 230 V AC. Inductive or capacitive 3 A / 8 A
• Requires external 7 to 24 V DC supply. Not battery powered
• Compact: 39x33x18 mm, fits standard junction boxes and DIN rail
• Up to 1,000 m encrypted Jeweller range in open space
• Thermal protection at 65°C ambient or 85°C internal, jamming detection built in
