Dimmer with dual-channel transmitter rH-D1S2 RH-D1S2

Intelligent lighting control with rH-D1S2

This wireless dimmer module with a two-channel transmitter, known as rH-D1S2, is a key element of the F&Home Radio system. The device combines light dimming functionality with the ability to monitor the status of two independent contact inputs. This allows you not only to adjust the light intensity but also to receive information about the change of state of devices connected to it – e.g., a door opening or an alarm being triggered. The module transmits this data to the central server of the radio system, enabling remote control and automation.

Versatile application and easy integration

rH-D1S2 is ideal for both new installations and for modernizing existing systems. Radio communication at a frequency of 868 MHz ensures a stable connection and a range of up to 100 meters in open space. Two-way data transmission guarantees reliable operation, and the possibility of coding increases system security. The module is compatible with various types of loads – from traditional light bulbs to modern LED light sources and fans (up to 120W for capacitive/inductive loads and 180W for resistive loads).

Installation and safety

The rH-D1S2 module is designed for mounting in flush-mount boxes with a diameter of 60 mm. It has built-in overheating protection and a current limiter (1A), which ensures safe operation of the device. Operation at a temperature of 0°C to +45°C and humidity up to 85% (without condensation) allows it to be used in various environmental conditions. Additionally, the module has an IP20 protection rating, which protects it from accidental contact with live wires. Autonomous mode ensures operation even in the event of a temporary loss of connection with the server.

This dimmer module operates at a supply voltage of 230 V AC with a tolerance of -20% to +10% and consumes only 0.4 W of power. Communication takes place at a radio frequency of 868 MHz with a signal power of 9 mW, providing a range of up to 100 meters in open space. The switching time from 0 to 100% takes from 0.2 to 30 seconds. It has two contact inputs with a voltage of 230 V and an input current of 1 mA. The device is adapted to work at a temperature of 0°C to +45°C and air humidity up to 85% (without condensation). The IP20 protection class provides basic protection against contact with live wires. The module can handle an output load of up to 120 W for capacitive and inductive loads and up to 180 W for resistive loads.
