Transceiver antenna for home automation systems

Transceiver antenna for home automation systems: connected to a PC or a home automation control unit, via RS485 bus, it allows the home automation control unit to receive all the commands coming from the radio thermostats via MODBUS® RTU protocol. Unlike the DA0411, the DA0421 can also transmit actuation commands to one or more DRR42M receivers whose output relays can directly drive actuators, valves, dampers, fans, etc.

Maximum 32 DRR42M receivers can be driven by one DA0421.
