  1. Mark Stevens –

    Great little device for my smart home setup. I installed this Ajax Relay to trigger my electric gate, and it works flawlessly through the app. Installation was straightforward since it’s so compact. Very happy with the quick delivery from the shop.

    Mark Stevens –

Can I wire this relay to control high-consumption industrial motors?

The relay is rated for a maximum load of 5A at 36V DC. For complex industrial applications or wiring diagrams involving high-inductive loads, please reach out to our technical support team at [email protected] for expert advice before installation.

Is the 38204 Ajax Relay sold here the official EU version?

Yes, we only stock the official EU version of the 38204 Ajax Relay. This ensures it is fully compatible with EU-frequency Ajax Hubs, receives all official firmware updates, and is not subject to region-locking. Apsardze24.lv is an authorized partner, ensuring you receive genuine hardware.

What are the specific power supply requirements for this controller?

The device requires a power supply between 7V and 24V DC. It is designed strictly for low-voltage direct current; it cannot be powered by or directly switch 110V/230V AC mains power. Always ensure your power source matches these specifications to avoid damaging the unit.

Can I use the Ajax Relay to remotely restart my internet router?

Yes, this is a common use case. By wiring the relay into the router's DC power line, you can use the mobile app to temporarily break the circuit and restore it, effectively performing a remote reboot of your network equipment from anywhere in the world.

Which mobile app do I need to control the 38204 Ajax Relay?

To manage the device, you need to download the official 'Ajax Security System' app, which is available for both iOS and Android. Through the app, you can switch equipment on or off with one click, monitor real-time voltage levels, and configure automated scenarios.

What does 'dry contact' mean for the 38204 Ajax Relay functionality?

A dry contact means the relay's output is electrically isolated from its power supply. This allows the 38204 to act as a simple switch for an external circuit (0-36V DC) without injecting its own voltage, making it ideal for controlling gates, valves, and electric locks that have their own power source.

What happens if my 38204 Ajax Relay malfunctions after a year?

We provide a comprehensive 2-year warranty for both private individuals and business clients. Since our primary service center is located in Riga, Apsardze24.lv can offer fast local repairs or replacements, so you won't have to deal with the long wait times of shipping products back to a manufacturer abroad.
