The ezTCP SIG-5430 by Sollae Systems is a temperature gateway that reads the temperature value from a PT100 resistance temperature detector and sends it to an ethernet network using the Modbus TCP protocol. Users can remotely read the temperature by using any Modbus Software/Apps or HMI device.

Users can config thresholds to make it trigger another Modbus TCP device that has digital output ports. This is called an Internet Switch.

We provide a free software and a smartphone app, called ModMap, which can connect to devices to read the temperature.
