Allen-Bradley | 2080-SERIALISOL | Communication Plug-in Module

Product Description: Allen-Bradley 2080-SERIALISOL

The Allen-Bradley 2080-SERIALISOL is a serial isolation communication plug-in module designed for use with the Micro800™ family of programmable logic controllers (PLCs). This module provides an isolated RS-232/485 serial communication port , enabling the Micro800 controller to connect safely and reliably to external serial devices while protecting the controller from ground loops and electrical noise. The 2080-SERIALISOL enhances communication flexibility and ensures safe data exchange in industrial environments where electrical isolation is essential.
