Triple relay radio module - long range rH-R3S3-LR RH-R3S3-LR

Triple Relay Radio Module – Control and Automation at Your Fingertips

The rH-R3S3-LR module is a versatile device combining the functions of relays and input contacts in a single module for DIN rail mounting. It is a key element of the F&Home Radio system, enabling remote control and monitoring of three independent electrical circuits. Thanks to radio communication, installation becomes more flexible and easier to implement, especially in facilities where wired installation is difficult to access.

Versatile applications and easy integration

This module is suitable for both home and commercial installations. It allows you to control lighting, gates, blinds or other electrical devices. Three input contacts allow you to connect monostable potential-free buttons, which allows for traditional control and integration with a home automation system. The relays, in turn, provide reliable switching of circuits with different load characteristics – resistive, inductive or capacitive, both in direct current (DC) and alternating current (AC).

Key features and benefits

• Three independent channels: Control three electrical circuits with one module – saving space and costs.
• Radio communication: Wireless communication with the F&Home Radio server provides installation flexibility and easy system expansion. Range up to 100 meters in open space.
• Input contacts: Possibility to connect three monostable potential-free buttons – traditional control and integration with automation system.
• Built-in thermal protection: Ensures safe operation of the device even under heavy load.
• DIN rail mounting: Quick and easy mounting in the distribution cabinet.
• Two-way transmission: The server receives information about the status of the input contacts and can control the relays.
• Local mode: Allows manual switching of all relays using a button on the housing – useful during servicing or failure of the radio system.
• Universal load: Relays support resistive, inductive and capacitive loads in AC/DC circuits.

Additionally, the module has thermal protection and radio transmission coding to increase the safety and reliability of the system. 230V AC power supply ensures compatibility with most electrical installations.
