Wireless Potential-free Relay

SAFE Dry Relay

Dry Relay is a modern wireless relay with a potential-free output, designed for convenient and safe remote control of electrical devices and appliances with power supply in the range of 7 to 24 V DC. Thanks to the relay output of NO/NC type (normally open/normally closed contact), which is galvanically isolated from the power circuit, maximum safety and universal use ("dry contact") are ensured. The output can be easily configured either to bistable mode for permanent activation or deactivation, or to pulse mode, where the relay activates only for a preset duration. Dry Relay thus offers a flexible solution for a wide range of applications in both security and smart home areas.

Description of the Device

Discover the Smart Home and Security Module!

Dry Relay stands out for its versatility and opens up a wide range of applications – whether you need to control electric locks, bolts, lighting, or other devices within alarm or automation systems. This module is an ideal choice for various types of installations. Thanks to its miniature dimensions, you can easily place it in a standard installation box, or simply attach it to a DIN rail using the SAFE DIN Holder bracket. Installation is also possible in a distribution box, server cabinet, electrical panel, or directly into a switch. Dry Relay thus offers maximum flexibility and easy integration into your system.

Wireless Control and Automation Easier Than Ever Before

Using scenarios, actions of automation devices can be programmed, such as Dry Relay or also Power Relay and Socket, which respond to alarm events, pressing a Button or operate according to a preset time schedule. Scenarios can be created and configured remotely directly in the ProSAFE app. The device is thus ideal not only for alarm installations, but also offers the possibility of full integration of the SAFE security system into a smart home or building automation, precisely where secure wireless control of devices powered by low voltage 7 to 24 V DC via relays is needed.

Smartly and Safely with Dry Relay

Secure connection with the central unit of the SAFE security system is guaranteed thanks to the encrypted communication protocol SAFE Keeper, which enables reliable data transmission up to a distance of 1,200 meters in open space. The Dry Relay device additionally supports convenient cloud firmware updates and is equipped with advanced protection against overvoltage and overheating, which ensures its long-term reliability and safe operation.
