Seitron Transceiver antenna for home automation systems DA0421

Transceiver antenna for home automation systems: connected to a PC or a home automation control unit, via RS485 bus, it allows all commands from radio thermostats to be received by the home automation control unit 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 control actuators, valves, dampers, fans, etc.
A maximum of 32 DRR42M receivers can be controlled by one DA0421.
