The ezTCP SIG-5431 is a remote I/O gateway equipped with 4 analog input ports and an Ethernet interface. The device is connected securely to the Sollae IoT Cloud via the MQTT protocol. The device allows monitoring data of various analog sensors from anywhere via a web interface.

Each individual analog port has three selectable measuring modes: voltage (0~5V), current (4~20mA), and current (0~20mA). This makes a single SIG-5431 able to work with many kinds of analog sensors.

Depending on the users' configuration, if the analog value in an analog input port passes through a predefined threshold, it can alert users via the web UI and/or send commands to control digital outputs on other devices (SIG-5451, SIG-5601).

Since the SIG-5431 is connected to the Sollae IoT Cloud, it benefits from various Sollae IoT Cloud features, such as a real-time, secure, user-defined event, alarming, and different web interfaces. It is very easy to use. The user just needs to connect to the Internet, sign into the cloud, register the device to the user's account and interact with the device via the web.
