Ajax Relay Jeweller Wireless Dry-Contact Relay, 7 to 24 V DC Powered

Overview

The Ajax Relay Jeweller is a wireless dry-contact relay that lets an Ajax system switch another device’s circuit on or off: an electric lock, a gate controller, a pump, an alarm panel input or any low-voltage equipment with a switched input. It is powered from 7 to 24 V DC and its contact is isolated, so it only closes or opens a circuit and supplies no power to it. It suits homes, shops and offices on an Ajax system that want automation beyond plug-in appliances.

Is it right for you?

• It suits switching electric locks, gates, garage doors, irrigation or ventilation controls from Ajax scenarios.
• Choose it when you need a dry contact: the device you control has its own power and only needs a switch closed.
• It needs a 7 to 24 V DC supply of its own and fits in a switchboard or junction box.
• For switching mains loads directly, the WallSwitch is the right device; for a plug-in appliance, the Socket.

Key features

• Dry contact rated up to 5 A resistive (3 A inductive or capacitive) on DC circuits, and up to 13 A resistive (8 A inductive or capacitive) at 110 to 230 V AC.
• Powered from 7 to 24 V DC, with up to 1 W standby consumption; the relay does not supply power to the devices connected to it.
• Pulse mode (0.5 to 255 s) or bistable mode, with normally open or normally closed contact state.
• Scenarios: on arming or disarming, by schedule, by alarm, by temperature, by humidity or CO2 level (with LifeQuality on the system), or by pressing a Button or touching a LightSwitch.
• Protection that switches it off when the supply drops below 6.5 V or rises above 36.5 V DC, or on overheating above 65 °C at the installation point or 85 °C inside the relay.
• Accepts cable of 0.75 to 1.5 mm² (22 to 14 AWG).
• Jeweller two-way radio, up to 1,000 m to the hub or range extender in open space, with communication loss detection after 36 s.
• Compact at 39 × 33 × 18 mm and 25 g, IP20, for -10 to 64 °C.

What else you need

An Ajax hub or range extender and the Ajax app, a 7 to 24 V DC supply for the relay, and the device whose circuit it will switch. Mount it on a DIN rail with the DIN Holder, which is sold separately, where possible. Scenarios by humidity and CO2 need a LifeQuality on the system.

Installation

Wire it into the switchboard or junction box with 0.75 to 1.5 mm² cable, powered from 7 to 24 V DC, and fix it with the supplied double-sided tape or on a DIN rail with the DIN Holder. It can be used outdoors only inside a sealed enclosure. An electrician or Ajax installer then adds it to the hub in the app and sets pulse or bistable mode.

Software and licences

Operating mode, pulse length, contact state and scenarios are managed in the Ajax app.

Before you buy

• DC power only, 7 to 24 V; it does not power the connected device.
• The DIN Holder is sold separately; double-sided tape is supplied.
• Outdoor use only inside a hermetically sealed enclosure.
• Black only.
