Two factory-paired modules; each provides one 4–20 mA analog input and one 4–20 mA analog output
Y401-0011-L LoRa Wireless Analog I/O Pair, 1AI/1AO
Single-channel point-to-point wireless analog I/O module
Y401-0011-L transfers a 4–20 mA signal between two factory-paired LoRa modules. Each module has one analog input and one analog output, with no digital I/O.
Key Features
Bidirectional signal transfer over a half-duplex LoRa link; no digital inputs or relay outputs
Up to 5 km standard; a 10 km option is available for selected configurations. Actual range depends on antennas and site conditions
Use an active current source with at least 10 V source voltage; power two-wire transmitters separately
Verify the supply-voltage and load combination before use; a 9 V supply does not establish operation at the 500 Ω maximum load
Validate analog output behavior during link loss and recovery before connecting a control load
