Smart modbus RTU RS485 devices for automation, data logging

Legacy industrial sensors and PLC devices that use Modbus RTU RS485 or 4-20 mA analogue output can now be wirelessly connected to cloud platforms without replacing existing hardware. AHOYSYS Modbus converters act as transparent bridges, reading data from any Modbus slave device and transmitting it over WiFi, 2G, or LoRa to MQTT brokers, cloud dashboards, or SCADA systems.

This enables Industry 4.0 upgrades at a fraction of the cost of replacing field instruments. Energy meters, flow meters, pressure transmitters, temperature controllers, and PLCs can all be retrofitted with wireless connectivity using AHOYSYS converters.
