Do you need to open and close a circuit with a high voltage or current? Use the relay from the Troyka Module series. It's easy to work with and extremely easy to use - no soldering, no small components, no confusion. Nothing needs to be set up, everything is ready for you to use!

At its core, the relay is just a mechanical switch that can be controlled by a microcontroller such as an Arduino. There is no electrical connection between the control electronics and the switched load. This means that your electronics are safe and that no interference will foil your plans. If you use our relay, it is possible to turn on and off electrical appliances, even those that are plugged into 120/220 V outlets. Combining this with other Troyka Modules, you can finally create the smart home of your dreams!

All the electronic strapping necessary to control the relay is already built into the module, and there is an LED which tells you if the relay is closed.

This relay has a normally open (NO) contact, but also can be converted to a normally closed (NC) contact. This is useful when creating security systems and the de-energizing of the alarm should lead to a trip that sounds an alarm.

The relay operates when a high signal is fed to the input of the module. In this instance, the relay is driven by a built-in power gate, which makes it possible to use any voltage from 3 to 5 volts as a control signal. Therefore, the module can be controlled from most boards, including a Raspberry Pi.

The Troyka Module series relay module is based on the RTD14005, and can be neatly placed on the front panel of your device, fastened with М3 screws.


Connect via the 3-pin jumper cable to send a signal to the module.

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

The terminal block securely holds the commutated wires using screws.

The relay can control a load of up to 16 A at a voltage of 250 VAC or 28 VDC. Commutaion of DC voltages over 28 V is possible too, however, the maximal current will be lower in this case.

Attention! If you are in doubt as to how to connect an electrical appliance to the relay that works on a common 120/220 V network and are having doubts or questions about how this is done - stop! It is possible to start an electrical fire or even kill yourself. Make sure that you fully understand the principles of the relay and the dangers that are associated with high voltage. Some mistakes cannot be made twice.
