IoT gateway MGLW868

Modbus RTURS-485LoRaWAN

Overview
Fully configurable IoT gateway that reads and writes Modbus data and forwards it over the LoRaWAN radio network. Operates as a Modbus → LoRaWAN gateway and transmits data to a dedicated supervision platform.

General specifications

• Integration: Dimensions 90 × 57 × 67 mm; DIN-rail mounting.
• Modbus: Modbus RTU over RS485; read/write; master–slave support; periodic or conditional read requests; register-based alert thresholds.
• LoRaWAN: Modbus–LoRaWAN gateway function; 865–870 MHz band; adaptive data rate from 300 bit/s to 10 kbit/s; transmit power up to 14 dBm; forwarding to a dedicated supervision platform.
• Electrical: Supply 10–30 VDC; consumption (24 V): Tx(max) 25 mA / Rx(max) 10 mA; transmit power 24 mW (14 dBm).

Antennas
This product requires an external antenna. Recommended models to optimize coverage:

• ANT868-S — whip antenna (SMA connector)
• ANT868-O — omnidirectional antenna (N-female connector)
• ANT868-Y — directional antenna (FME-male connector)

Functions

• Sensor data collection: polls remote or isolated sensors; long-range transmission via LoRaWAN; access to real-time or historical values.
• Control and automation: remote control of actuators; implementation of automated scenarios; periodic reading of remote sub-meters.

Standards and certifications

• Compliances: CE
