The 2080-SERIALISOL module provides electrical isolation, allowing secure communication in industrial environments where electrical noise and interference are common. It helps protect the connected devices from voltage spikes and electrical disturbances.

The module supports various communication protocols and can be configured to communicate with a wide range of devices, such as human-machine interfaces (HMIs), bar code scanners, printers, and other serial devices. It typically connects to the PLC's serial port and provides the necessary electrical isolation for reliable and robust communication.
