PL140 Carrier Data Terminal
The PL140 carrier data terminal is a transparent transmission module designed and optimized for low-cost commercial and general industrial applications, ideal for control and small-data collection scenarios. Combining power-line carrier (PLC) and LoRa communication technologies, it requires no cabling and supports active-standby redundancy to reliably transmit user data to connected devices. The PLC feature enables communication during power outages and operates over twisted pair, coaxial cable, and power lines (bare wire, DC, single-phase AC, and three-phase AC). LoRa supports channel and air rate selection to maximize data delivery rates.
