The Ajax Relay Module is a versatile and efficient solution for remote control of electrical systems via a wireless network.

The module is compatible with both low-voltage systems and household electricity, making it ideal for controlling a variety of devices, from lighting and gates to valves and electromagnetic locks.

The relay module is equipped with a dry contact and operates without a galvanic connection to the unit's power supply, which allows it to be used in a variety of electrical installations.

One of the most prominent features is the flexible operating technology that offers both bistable and pulse modes to suit different types of use.

In pulse mode, the user can adjust the duration from 0.5 to 255 seconds, allowing the module to be set exactly as needed.

The relay module is also equipped with a voltage protection that protects the device against voltage spikes and ensures long durability and operational reliability.

Installation is easy and takes only a few minutes. By connecting the module to the Ajax hub via the Ajax app, users can quickly access their devices.

The miniature designed unit (39×33×18 mm) fits perfectly into electrical junction boxes and electrical panels, and an external antenna ensures stable communication up to 1000 meters in open terrain.

The Relay module is built with Ajax's Jeweler radio technology, ensuring fast and secure communication between devices.

The encryption and authentication prevents forgery and hacking, making the system both secure and reliable.

The relay module can handle both resistive and inductive loads and supports a maximum current load of 13A at 230V~ and 5A at 24V⎓.

The relay module is ideal for use in both small and large installations and can be used to control a range of electrical devices.

With support for automation via the Ajax apps, Relay can be easily integrated into automated scenarios, such as turning on lights when an alarm is activated, or controlling valves and gates based on schedules or alarm events.

Frequently asked questions

What is Ajax Relay?
Ajax Relay is a wireless relay with potential-free (dry) contacts used to control current or signals in low and high voltage installations via the Ajax system.
What does potential-free (dry) contacts mean?
This means that the relay's output is electrically isolated from its own power supply, allowing it to be used for both low-voltage and 230 V installations as well as for simulating buttons or switches.
What is the difference between Ajax Relay and Ajax WallSwitch?
Ajax Relay has potential-free contacts and requires an external power supply (7–24 V DC). Ajax WallSwitch is a ready-made 230 V relay that is powered directly from mains voltage and does not have potential-free contacts.
When should you choose Ajax Relay instead of WallSwitch?
Ajax Relay is used when you need to control low voltage, signal control, magnetic locks, gates, valves or other equipment that requires potential-free contacts.
When is Ajax WallSwitch better suited?
WallSwitch is best suited for turning on and off 230 V devices such as lighting, heating elements or sockets where potential-free contacts are not needed.
Is power supply included for Ajax Relay?
No, Ajax Relay requires an external power supply of 7–24 V DC, which is not included.
How much load can Ajax Relay handle?
Maximum load is 5 A at 36 V DC and up to 13 A at 230 V AC (resistive load). For inductive loads, the maximum values are lower.
Can Ajax Relay work in pulse mode?
Yes, the relay can operate in pulse mode with adjustable pulse time from 0.5 to 255 seconds, or in bistable mode.
Can Ajax Relay be used for electric locks and gates?
Yes, it is one of the most common areas of use thanks to the potential-free contacts.
Does Ajax Relay work standalone?
No, Ajax Relay requires a compatible Ajax hub to function.
Can Ajax Relay be used in scenarios?
Yes, it can be used in automations, for example for alarms, schedules, temperature, humidity, CO₂ levels or via Ajax Button.
Does Ajax Relay have protection against overheating and overvoltage?
Yes, it has both temperature and voltage protection that automatically cuts off the power at abnormal values.
Who should install Ajax Relay?
Installation must be carried out by a qualified electrician or installer.
Does Ajax Relay work indoors or outdoors?
Ajax Relay is intended for indoor use. For outdoor installation it must be placed in an enclosure.
Do I need a subscription for Ajax Relay?
No, no subscription is required. A subscription is only needed if the system uses a SIM card or is connected to an alarm center.
