Three-state relay with two-channel transmitter F&Home RADIO rH-TSR1S2i F&F

The module sends information about shorting and opening contacts to the system. It controls a relay that can switch on bidirectional electrical loads. Communication with the server is by radio.

The module has two physical inputs for connecting two monostable buttons, and two relay outputs. The load of the relay contacts can be resistive, inductive or capacitive, both in DC and AC circuits.
