Two-channel relay with two inputs of the F&Home RADIO system.
The rH-R2S2 is a combination of two relays and two contact inputs. The module sends information about opening or closing of the contacts to the system and controls the relays that can activate any electrical circuits. Communication with the server is done via radio. The module has two physical inputs for connecting two momentary potential-free contacts and two inputs of the relay. The load of power input can be resistive, inductive and capacitive, both in direct and alternating current circuits. Pressing the button on the housing for less than 1 second switch on or switch off all relays simultaneously.
If the module is disconnected from the server, it goes into autonomous mode. Short press of the button connected to contact 1 or 2 switches on or off the relays.
Conditions for autonomous mode to activate:
1. Correct connection of S1 and S2 contacts with the button;
2. Option Offline: autonomous mode is enabled in the Installer settings.
The rH-R2S2 module is represented by an object, which consist of two binary inputs and two binary (bistate) outputs of the relay, separate for each physical input. The input of the object is used for controlling the relay channels, and the information about operating state of the relay is feed on the output. The element has also two binary (bistate) inputs and two binary outputs that correspond to a physical input. Closing or opening the contact causes the logical state to change at the output.
