RTD Astra-Y

RTD – Receiving Terminal Device.

RTD is designed to receive notifications over the radio from registered TTDs, decode and send notifications to three built-in LED indicators, two signal relays and one OC output, as well as via the LIN interface in standalone operating mode or via the RS-485 interface in extended operating mode.

The main purpose is the organization of centralized monitoring via radio channel (433 MHz) of cottage settlements, industrial facilities, etc.

The radio communication between the RTD and the TTD is two-way.

RTD supports up to 48 of TTD in standalone operating mode and up to 250 of TTD in extended operating mode.
