The TERRA-IO is a network programmable I/O device with serial port, adapted to automation and monitoring applications. The TERRA-IO is a TERRACOM device without audio inputs and outputs. Although it can be used in audio applications where you will need a lot of analog I/O, the input contacts and the relay outputs will be useful in industrial and home automation applications or when you need to monitor contact closures. The serial link can be used for IP tunneling between a PC and a device like a sensor for tele monitoring. Thanks to the SNMP, the management is adapted to big systems.
