Don't Settle for an RTU - Use a Complete SEL Integrated Solution for Remote SCADA, Protection Settings Maintenance, Oscillographic Event Retrieval and Analysis, Sequential Event Reporting, and More. 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. Sixteen additional optoisolated inputs and four programmable output contacts. SEL-2701 Ethernet Processor. SEL-2711 Modbus Plus Protocol Card. 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.
