2. Key technical differences
RT5BF01 — Standard wireless RS485 communication
-
Frequency range: 426–508.5 MHz
-
Advertised open-area range: 800–1,000 m
-
Baud rates: 9,600, 19,200, 38,400 and 115,200 bps
-
DC supply: 8–25 V
Best choice: Replacing a long RS485 cable between compatible serial devices.

RT24G01 — High-speed wireless RS485
Eletechsup advertises an air data rate of up to 2 Mbps and describes this model as a fast wireless transceiver. The air data rate is not the same as the effective RS485 application throughput.
Best choice: Projects where higher wireless transmission speed is a priority. Confirm actual serial throughput and range for your application.
RT4AE01 — Multi-interface wireless serial communication
Available interface versions include RS485, RS232 and USB, with 433 MHz and 868 MHz options. Eletechsup lists an advertised open-area transmission distance of approximately 500 m.
Best choice: Integrators who need to connect different types of serial equipment or a computer to a remote device.
RTTXA08 / RTRXB08 — Wireless remote I/O with feedback
-
8 input channels on the transmitter
-
8 relay outputs on the receiver
-
LED feedback indicates the receiver's switch status
-
Advertised open-field range: up to 2 km
-
Receiver relay rating: up to 10 A, subject to the specified load conditions
Best choice: Remote switching and control where users need visual confirmation of the receiver's output state. This is a dedicated I/O control system rather than a transparent RS485 modem.
