The IO HUB is our new generation Ethernet HUB GPIO module (GPIO “General Purpose Input/Output”) suitable for electrical devices control and monitor over the Internet. It connects a set of 8 SPDT relays, 8 analog inputs and 8 optically isolated digital inputs to Ethernet and make them available through the SNMP protocol. It also provides a dedicated input for temperature probes, a RS485 interface and a built in real time clock. It can be accessed locally or remotely via web browser for configuration.

The network parameters (IP address, gateway and mask) and other options (e.g. the maintenance mode) can be locally set by means of the built-in display and keyboard allowing an easy installation without the needs of a PC.

Test operations are possible via the local user interface as the current value of all the inputs and outputs is shown on the display. Moreover, in maintenance mode, the status of each output relay can be manually forced. All the electrical connections are made by plug-in connectors for an easy installation and removal.
