Relay Jeweller

External power supply

7–24 V⎓

The relay does not supply additional power to devices connected to it.

Energy consumption 

up to 1 W

In standby mode.

Cross-sectional area of the cable

0.75–1.5 mm² (22–14 AWG)

Maximum resistive load

up to 5 A at 24 V⎓

up to 13 A at 110–230 V~

Maximum inductive/capacitive load

up to 3 A at 24 V⎓

up to 8 A at 110–230 V~

Voltage protection

minimum — 6.5 V⎓

maximum — 36.5 V⎓

Once the supply voltage exceeds the specified levels, the relay turns off automatically.

Temperature protection

over 149 °F at the installation site

over 185 °F inside the relay

Jeweller communication technology

Proprietary wireless communication technology to transmit commands, alarms, and events.

Key features:

• Two-way communication.
• Advanced anti-sabotage.
• Block encryption featuring a dynamic key.
• Instant notifications.
• Remote control and configuration in Ajax apps.

Frequency bands

866.0–866.5 MHz
868.0–868.6 MHz
868.7–869.2 MHz
905.0–926.5 MHz
915.85–926.5 MHz

Maximum effective radiated power (ERP)

up to 25 mW

Radio signal modulation

GFSK

Radio communication range

up to 3,250 ft

Between the relay and a hub (or a range extender) in an open space.

Encrypted communication

All stored and transmitted data are protected by block encryption featuring a dynamic key.

Frequency hopping

To prevent radio interference and jamming.

Control via smartphone

The user can set up the relay configurations and receive notifications in an Ajax app.

Automation scenarios

• By arming/disarming
• By schedule
• By alarm
• By temperature
• By humidity¹
• By CO₂ concentration¹
• By touching LightSwitch / pressing Button

¹Scenarios by humidity and CO₂ concentrations are available when LifeQuality Jeweller is added to the system.

Adjustable pulse duration

from 0.5 to 255 s

Operation modes

• pulse
• bistable

Contact state

• normally open
• normally closed

Protection against spoofing

device authentication

Communication loss detection

after 36 s

Detection time depends on the Jeweller or Jeweller/Fibra settings.
