Features:
KQ-130F is a single row 9-pin small size high-performance carrier data transceiver module.

Designed for on 220V AC, strong interference, strong attenuation and long distance required environment, reliable data transmission.

A frame continuous send maximum length is 252 bytes or less, from 1 to 252 defined by the user, and the module will not send redundant data.

TVS diode protection against lightning stroke, the PCB wiring and components selection are all designed for wide temperature and high voltage resistance.

Suitable for meter reading, street light, intelligent household, fire fighting, building control and other applications that need power to send data.
