Product Description

The multi-function LoRa radio model HLR-A4C4 can handle four analog inputs, four contact inputs, and RS-485 (Modbus) communication in one device. It can send data and perform monitoring through LoRa wireless to an IoT gateway.

The device uses LoRa (*) for wireless communication. LoRa allows line-of-sight communication up to 5 km with the HLR-GW IoT gateway. Because of this long range, the system can communicate in places where normal 920 MHz low-power wireless could not reach without a repeater. Many customers value this advantage.
*This device uses LoRa Private.

Features

One device handles analog inputs, contact inputs, and RS-485 communication, making it useful in many locations and ideal as an IoT starter kit.
It supports four analog inputs, with status transitions (graph display) and current values shown on the IoT gateway.
It supports four contact inputs, allowing ON/OFF monitoring and counting through the IoT gateway.
Data can be sent wirelessly through LoRa or by cable through RS-485 (Modbus).
The device can supply DC5V or DC24V power to connected sensors.
An external antenna can also be attached.
