Distributed I/O

Eaton’s substation-grade SMP distributed I/O platforms are specially designed to meet the requirement for distributed I/O in modern utility substation automation systems. Both SMP distributed I/O platforms support binary inputs and binary outputs, as well as analog inputs. They operate with AC or DC voltage, and communicate over serial RS-485 or TCP/IP using fiber or copper Ethernet. Both platforms, the SMP IO-2230 and the SMP I/O, can be integrated with the SMP Gateway or used as standalone I/O modules that connect directly to a master station. The SMP distributed I/O platforms are part of Eaton's grid automation system solutions.
