Overview
Y401-0011-L is a 1AI + 1AO LoRa wireless analog I/O module for extending one 4-20 mA signal channel between separated locations. A typical system uses two factory-paired modules: the analog input on one module is reproduced at the corresponding analog output on the other, with the same operation in reverse.
Typical applications
- Replace long 4-20 mA control or measurement cables between two points.
- Remote pressure, level, flow and other analog signal monitoring.
- Industrial, agricultural, aquaculture and hydrological monitoring projects.
How it works & selection
- Device A AI1 to Device B AO1.
- Device B AI1 to Device A AO1.
- Each unit requires its own DC power supply at the installation point.
Selection notes
Confirm the 4-20 mA source and receiver type, loop power, receiving load, installation distance and antenna position. The analog input is an active 4-20 mA input, not a transmitter loop power supply. The analog output is an active current source.
Sold as one factory-matched pair (2 modules). Each module requires its own local power supply.
Y401 series demonstration
Demonstration with the Y401-22-L model. Channel counts and signal types depend on the selected model.
