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.

Core features

  • Seamless networking facilitated through the SMP distributed I/O’s Ethernet and RS-485 ports, and by relying on the industry-standard DNP3 protocol
  • Supports also IEC 61850 and GOOSE messaging (SMP IO-2230)
  • Integrated micro-PLC and full integration with the SMP Gateway management application for the SMP IO-2230
  • The SMP IO-2230 complies with industry cybersecurity standards (certified under UL 2900-2-2)
  • Designed for growth: up to 64 I/Os for the SMP IO-2230 and 32 I/Os for the SMP I/O
  • Part of the Eaton RTU replacement solutions

Leading cybersecurity

Eaton's SMP IO-2230 is the first utility substation automation technology certified under UL 2900-2-2.

Typical applications

When using a standalone distributed I/O unit, a master station can monitor and control remote devices using the DNP3 protocol, with accurate IRIG-B time-stamping, effectively replacing a traditional RTU. It is designed to provide seamless integration with the SMP Gateway automation platform. It transparently adds support for discrete and analog I/O to the automation platform. Eaton's SMP Gateway extends the SMP I/O platforms through its extensive protocol support, advanced logic processing, built-in HMI and security features.

Supporting IEDs in distributed systems

The architecture of automation systems has moved from a centralized approach, based on large RTUs, to distributed systems based on Intelligent Electronic Devices (IED) with built-in I/O capability. However, not all I/O can be managed by the IEDs and numerous functions require an I/O processor. Eaton’s SMP distributed I/O platforms are specially designed to fill this gap.
