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. Our SMP distributed I/O platforms are the Linux-based SMP IO-2230 and the SMP I/O. These platforms support binary inputs, binary outputs and analog inputs; they operate with AC or DC voltage. Both platforms communicate over serial RS-485 or TCP/IP using fiber or copper Ethernet and 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.
Substation-gradeThe SMP distributed I/O platforms are robust substation-grade hardware devices that meets IEEE 1613 and IEC 61850-3 standards for vibration, electrical surges, fast transients and extreme temperature ranges. |
Both platforms are designed for growth and flexibility
|
Seamless networkingBoth platforms include Ethernet and RS-485 ports. They use the industry-standard DNP3 protocol. |
Reduced engineering effortThe SMP distributed I/O platforms save on cabling, commissioning and configuration time, especially when it is used with the SMP Gateway automation platform. Their removable connectors speed up hardware changes. |
ScalabilityThe SMP IO-2230 has an universal power supply with a wide input AC and DC voltage range as well as software configurable voltage ranges on binary inputs. |
CybersecurityThe SMP IO-2230 provides secure remote management capabilities; it has an integrated firewall and can be securely accessed for maintenance from Enterprise Management Software (IMS). Both SMP distributed IO platforms are accessible for secure remote maintenance via the SMP Gateway automation platform. |
Accurate dataThe SMP distributed I/O platform’s error-detection features ensure data integrity between the data point and the control center. They also support IRIG-B synchronization for precise timestamping. |
General specificationsThe SMP IO-2230 is the latest I/O platform from Eaton and is fully integrated with the SMP Manager’s software and tools and includes many new features that will greatly enhance user experience. It can contain up to 64 I/O and has advanced security features and programmable logic capabilities. |
10-year warrantyAll Eaton’s distributed I/O platforms are designed to operate without any maintenance for their entire lifetime, when used under normal conditions. The SMP IO-2230, our latest automation I/O platform, now comes with a 10-year limited warranty, the terms of which are described in the 10-year warranty on SMP Products document which is available in the Resources section under Selling policy and T&Cs. |

I/O configurationUp to 64 I/Os with flexible I/O configuration base on four I/O rows, each with the possible following I/O configuration: 16 BI or 16 BO (relays) or 16 HBO or 8 BI and 8HAI. Where HAI corresponds to high isolation analog input and HBO corresponds to fast speed and high-current interrupting binary output. |

General specificationsThe SMP I/O is composed of a base unit that can accept up to four field-installable I/O cards. The base unit provides two programmable form-C output relays, RS-485 and Ethernet communications interfaces, and an IRIG-B interface. All wiring is on the rear panel through removable terminal blocks. The front panel displays the status of the device and the state of all I/O signals. A Local/Remote control disables all control commands from the master station for operator safety during system maintenance. |

I/O configurationThe SMP I/O base unit can accept up to four field-installable I/O cards. The base unit provides two (2) programmable form-C output relays. |
Binary input cardThe binary input card provides 8 electrically independent opto-isolated connections. Various binary input card models are available for all commonly used voltage ranges. |
Control output card (binary output)The SMP I/O supports up to 18 control relays with the 2 form-C included in the base unit and the two binary output cards that can be installed in the bottom row. The high load carrying capability reduces the need for interposing relays.
|
Analog input cardThe analog input card has 8 isolated inputs that can be used to measure either voltage or current values. It is designed for DC value measurement only. The analog card is equipped with a Delta-Sigma 16 bits ADC for each channel and is factory calibrated to ensure high accuracy reading over all the operation temperature range. There are two models of analog input card, the standard model and the high isolation model. |
