SIG-5441 ezTCP 4-Port Digital Input I/O Gateway to Sollae IoT Cloud

The ezTCP SIG-5441 is a remote I/O gateway equipped with 4 digital input ports and an Ethernet interface. The device is connected securely to the via the MQTT protocol. The device allows monitoring the state of equipment/sensors from anywhere via a web interface.

Each individual digital input also has a counter function. This makes the SIG-5441 not only suitable for state monitoring but also counting applications.

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

Since the SIG-5441 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.
