Eaton’s substation-grade SMP distributed I/O platforms of the SMP IO-2000 series are specially designed to meet the requirements for distributed I/O in modern utility substation automation systems. This family of products is Linux-based and includes the evolutive SMP IO-2230 platform which supports binary inputs, binary outputs and analog inputs and the SMP IO-2330 system, with four models pre-mapped to specific I/O configurations. All models communicate over serial RS-485 or TCP/IP using fiber or copper Ethernet and can be integrated with the SMP Substation automation platform or used as standalone I/O modules that connect directly to a master station.
The SMP I/O is a robust substation-grade hardware platform that meets IEEE 1613 and IEC 61850-3 standards for vibration, electrical surges, fast transients and extreme temperature ranges.
The SMP I/O input and output cards can be added in minutes, without removing the unit from the rack.
The SMP I/O includes 1 Ethernet and 1 RS-485 port. It uses the industry-standard DNP3 protocol.
The SMP I/O saves on cabling, commissioning and configuration time, especially when it is used with the SMP Gateway. Its removable connectors speed up hardware changes.
The SMP I/O’s error-detection features ensure data integrity between the data point and the control center. It supports IRIG-B synchronization for precise timestamping.
The 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.
