• Simple, Complete Integration
  Link all substation intelligent electronic devices (IEDs) into a single, low-cost configurable contact point for SCADA, local human-machine interface (HMI), dial-in access, dial-out notification, and overall substation integration applications. Link multiple communications processors to provide redundant communications paths when necessary.
• Two Plug-In Protocol-Processor Card Slots Support SEL-2700 Series Cards
  Provide communication on hardware-specific local area networks. The SEL-2711 Modbus^® Plus Card connects with Modbus Plus networks. The SEL-2701 Ethernet Processor interfaces with fiber and copper Ethernet networks and includes support for Telnet, FTP, DNP3 LAN/WAN, IEC 61850 UCA2, and the OSI, TCP, and UDP stacks.
• Automatic Database
  Collect, store, and forward meter reports, targets, digital input status, event reports, demand meter reports, and more. Use the optional Flash memory for nonvolatile storage.
• Modbus^® Slave, DNP 3 Level 2 Slave, and ASCII Serial Protocols
  Provides easy-to-configure support for these popular serial protocols. SCADA links, local HMI, and dial-in modems can access data from multiple IEDs or communicate directly with individual IEDs.
• Programmable Logic Controller (PLC) Functions
  Use Boolean and arithmetic operators to create logical schemes to produce and forward information or perform control. Reduce overall system costs and improve system reliability by reducing the number of auxiliary devices.

• Sixteen additional optoisolated inputs and four programmable output contacts.
• Two MB Flash memory.
• Two slots accept SEL-2701 Ethernet Processors and SEL-2711 Modbus Plus Cards.
• Rack-mount or panel-mount hardware.
• Conformal Coating—Protect equipment from harsh environments and airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.

• Use plug-in cards in the SEL-2030 to connect IEDs to Ethernet or Modbus Plus networks.
• Eliminate or reduce the need for SCADA RTUs.
• Simplify, improve the reliability, and reduce the total cost of SCADA systems by using the SEL-2030 to collect and scale meter data, and also to collect targets, contact input status, and fault location data directly from relays. Use the contact outputs of relays and other IEDs for control. Directly support Modbus RTU Slave and DNP3 Level 2 protocols for links to RTUs or masters.
• Connect IEDs that do not support Modbus to a Distributed Control System (DCS). The communications processor provides faster updates to the DCS than would a multidrop system because it groups data for more efficient multiple-register or block access. Arithmetic functions can change scaling, calculate virtual analog inputs, and compare analog values to thresholds. Use SELOGIC^® control equations to combine digital inputs to initiate and qualify automatic control, or for interlocks.
• Support local HMI on a PC or industrial computer using the SEL-2030 as a communications hub for gathering data from and directing control commands to IEDs in the substation. Local event report collection, settings management, and data archiving may also be included in the local HMI.
• Set the communications processor to detect critical conditions and dial a pager. Send an ASCII message to an alphanumeric pager.
• Use the SEL-2030 as a hub to enable low-cost, point-to-point fiber-optic links that isolate equipment from hazardous and damaging ground potential rise; eliminate RFI, EMI, and communications system ground loops; and allow longer signal paths than possible with EIA-232 copper connections.
• Acquire and forward information from relays and specialized equipment monitoring devices to maintenance databases and expert systems.
• Use SEL-5020 Settings Assistant Software to prepare settings and communicate with the communications processor.
• Use with SEL-5040 Power System Report Manager Software to automatically gather relay event reports and manage them with a database.
