Schweitzer Engineering Laboratories SEL-2032 Communications Processor Relay

SEL-2032 Communications Processor from Schweitzer Engineering Laboratories is a substation‑scale data hub that consolidates IED data over a single cable or fiber link (with SEL‑2810 transceivers) to feed multiple masters and support engineering access. Building on the SEL‑2030, the device adds enhanced power‑user and SCADA features to collect, process, and forward data from both new and existing substations, while providing a dedicated connection point to IEDs for engineering and maintenance. It supports synchrophasor data collection from select SEL‑300 and SEL‑400 series relays and can map phasor values to common SCADA protocols such as DNP3 or Modbus for use in energy management systems and state estimation, enabling integration with SCADA masters, EMS, RTUs, PLCs, and HMIs. By enabling time synchronization over a single cable or fiber pair and consolidating communications traffic, the SEL‑2032 facilitates coordinated monitoring, control, and data distribution across multiple devices in a unified interface.
