SS10680 Modbus MQTT IoT Gateway

The SS10680 gateway is a device that provides a RS485 serial interface for Modbus RTU master protocol and an ethernet interface for Modbus TCP master and SSL/TLS MQTT protocols featuring a low-profile format which makes it suitable for DIN rail mounting inside industrial electrical cabinets.

Electrical connections are available via plug-in screw terminals. The full galvanic isolation ensures a good protection against interference present in industrial environments.
A dedicated hardware Watch-Dog manages the automatic reset of the device. Signalling LEDs allow an immediate diagnosis of device operation. The device power supply requires a voltage between 10 Vdc and 30Vdc. The device is protected against power supply polarity inversion.
