Three-channel relay with three-channel transmitter for DIN rail rH-R3S3 RH-R3S3

Smart electrical installation control with rH-R3S3

The rH-R3S3 three-channel relay with transmitter is a module of the F&Home Radio system, designed for mounting on a DIN rail. The device combines the functions of three relays and three control inputs, enabling comprehensive management of electrical circuits. It is an ideal solution for both installers and end-users looking for a convenient and reliable way to automate their homes.

Versatility and functionality

The rH-R3S3 module allows remote control of three independent circuits, as well as monitoring the status of three contact inputs. Thanks to two-way radio communication (868 MHz), it provides a quick and reliable response to commands. The ability to connect monostable potential-free buttons allows integration with existing infrastructure, e.g., doorbells or light switches. The relays can handle resistive, inductive and capacitive loads in AC and DC circuits, making them a universal solution for various applications.

Safety and reliability

The device has a built-in thermal protection, protecting against overheating and damage. Mounting on a 35 mm DIN rail ensures stability and ease of installation. Additionally, the module has a button allowing local switching on or off of all three relays – useful in emergency situations or during installation testing. A radio range of up to 100 meters in open space guarantees comfortable control even from a greater distance.

Applications

• Lighting control: Switching lights on and off in different rooms.
• Gate automation: Controlling the opening and closing of a garage or driveway gate.
• Electrical appliance control: Switching on and off heaters, pumps or other electrical appliances.
• Alarm systems: Integration with an alarm system by monitoring the status of contact inputs (e.g., door/window opening sensors).
• Status monitoring: Checking the status of devices connected to contact inputs (e.g., water leak sensors).

The rH-R3S3 module is compatible with other devices in the F&Home Radio system, allowing you to create a comprehensive smart home system tailored to the individual needs of the user. 230 V AC power supply ensures easy integration with existing electrical installation.
