- 7-24 V⎓ power supply
- Pulse (1-255 s) or bistablemode
- Compatible with Ajax home automation and security systems
- Wireless communication via Jeweller protocol
- Low power consumption, suitable for systems with power supplies + battery backup
- Easy installation in electrical panels, junction boxes or remote devices
- Control via Ajax app for smartphones or central panel

Tax included
Ajax Relay: Dry contact for remote control 12-24V DC
Versatile configuration and low power consumption make Relay a universal tool for equipment control. The dry contact is not galvanically connected to the device's power circuit: it can be used in low- and high-voltage networks. Bistable and pulse modes are available. The relay can be easily powered by a power supply coupled with a backup battery.
- Pulse duration 1-255 seconds
- Power supply 7-24 V⎓
- Dry contact
Intelligent Safety with Relay Relay
Use automation scenarios so that your security system not only signals threats, but actively counteracts them.
- Anti-flooding system
- Scheduled water shut-off
- Automatic doors and shutters
- Scheduled heating
Advantages of using the Ajax Relay
Anti-flooding system
Set automatic water shut-off in case of washing machine failure or pipe breakage. Manage the facility's water supply via the app and according to schedule
Automatic gates or automatic barrier
Control opening and closing via the app and Button button. No compromise on convenience and security.
Electric locks
Controls opening and closing of locks via the app and Buton Button. Block access to rooms by alarm, or when you activate night mode, to sleep in peace.
Security smoke machine
Configure smoke machine activation by a detector alarm or DoubleButton emergency button. It is a reliable protection of people and valuables from thieves.
Motorized roller shutters and blinds
Control the equipment remotely by App, by pressing the Button button or according to the scenario: when changing the security mode, by time of day, by alarm.
SCA Lock
Configures the access control system (SCA) reader lock during system entry to prevent employees from accessing protected premises and avoid false alarms.
