YO Modbus is the bridge between the Modbus network and LoRaWAN. It allows to read data via Modbus RTU from Slave devices and send it via LoRaWAN.

One YO Modbus device provides capacity to create up to 150 Modbus queries and to send them in up to 30 different LoRa packets. These are sent in LoRA packets of up to 5 queries each (i.e. maximum of 30 packets).

The device is designed for mounting on standard 35 mm DIN rails in electrical switchboards. It occupies only one pole width like a standard single-phase overcurrent circuit breaker.

The RS485 input on which the Modbus RTU protocol works is galvanically isolated from the rest of the device modules for maximum protection.

Additionally, the device can be connected to protective earth (PE) cable so that the charges coming from the RS485 cable shielding will be slowly dissipated to the earth cable. It will lead to equipotential bonding in the Modbus network on the device side.

It can be powered by direct or alternating current over a wide voltage range of 6-30 VDC or 5-21 VAC respectively.

The device communicates wirelessly over LoRaWAN. We are a member of the LoRa Alliance, which is responsible for data transmission security.
