HUR series Modbus remote input/output (I/O) devices are designed for industrial applications.

HUR series Modbus remote I/O devices have been designed with advanced features, such as extended temperature range, wide power input range... etc. 
HUR series Modbus remote I/O devices offer various I/O combinations, which ensure greater flexibility and are compatible with different applications, making them the perfect choice for creating a cost-effective remote I/O system.

The HUR series features an RS485 serial interface for Modbus RTU connection or an ETH interface for Modbus TCP connection.

## And LoRaWAN?

For all modules in the HUR7xx and HUR8xx series, there are corresponding LoRaWAN versions: same number of inputs and outputs, plus the LoRaWAN module that allows transmitting the status of inputs and outputs and controlling them via the LoRaWAN protocol. The product code for LoRaWAN products differs only by the digit "1" after the HUR code.

For example
**HUR711** (**modbus**) ==> **HUR1711** (**LoRaWAN**)
**HUR721** (**modbus**) ==> **HUR1721** (**LoRaWAN**)

These are UNIQUE products in the LoRa world, both for their extremely competitive price compared to the competition, and for the number of I/Os present.
