Industrial 433mhz Lora Modem lorawan Gateway with 4AI 2AO for IoT Solution

Parameters of ZHC0661

• Introduction​ of Lora Modem ZHC0661

ZHC0661 is a low-frequency half-duplex LoRa data transmission terminal that supports point-to-point communication protocol. It has 4 channels of AI detection, 2 channels of AO output, AI range conversion, local logic and logic settings between devices, and supports AES communication encryption. The use of serial ports for sending and receiving reduces the threshold for wireless applications and can realize data transfer from serial ports to LoRa. LoRa has the advantages of concentrated power density and strong anti-interference ability. The communication distance of this product can reach 8000M (open field, antenna gain 3dBi, height greater than 2m, 0.268K air rate, default channel).

• What is digital radio?

A device that transmits rs232/rs485 interface signals through radio technology for data transmission and reception. It can also be called "wireless data transmission station". The data transmission station provides a transparent RS232/RS485 data transmission and reception interface, which is very convenient to communicate with PLC, sensors, industrial control screens, and intelligent Connect the meter and other equipment. The paired use of two digital radio stations can directly replace RS485 wired wiring. It can be widely used in power industry, water conservancy industry, energy industry, agricultural application, municipal industry, geological monitoring, industrial control and other fields.
