SEL Port Server

High-Density Serial-to-Ethernet Port Server

The SEL Port Server provides high-density serial-to-Ethernet connectivity for industrial and utility applications. It enables secure Ethernet access to serial-connected devices and comes with acSELerator RTAC SEL-5033 Software engineering tools for configuring, monitoring, and troubleshooting serial communications. Designed, manufactured, and tested to operate in harsh utility and industrial environments, every SEL Port Server is backed by a ten-year, worldwide warranty and no-cost support for the lifetime of the product.

Deploy High-Density Serial Connectivity

Centralize Ethernet access to large groups of serial-connected devices, such as relays, radios, and modems. The SEL Port Server provides 16 to 48 EIA-232/422/485 RJ45 serial ports and expands up to 96 ports when paired with SEL-2905 Serial Port Expanders. The SEL Port Server automatically detects and natively manages the expansion ports.

Streamline Configuration, Port Mapping, and Communications Visibility

Configure the SEL Port Server offline by using the Port Server Builder extension in acSELerator RTAC. The extension automates repetitive configuration tasks and enables software-defined port mapping. Local logging, Sequence of Events logging, Syslog forwarding, and Simple Network Management Protocol (SNMP) monitoring help centralize communications visibility. Status views, statistics, and event data are accessible through the device web interface and help engineers identify and troubleshoot communications issues.

Support Time Synchronization and SCADA Connectivity

Support time synchronization and distribution by using IRIG-B and Network Time Protocol (NTP)/Precision Time Protocol (PTP) clients. Synchronize time stamps across all connected devices and logs. The SEL Port Server supports SCADA connectivity and remote monitoring over Ethernet networks by using DNP3, Modbus TCP, and IEC 60870-5-104.

Built for Harsh Utility and Industrial Environments

Built on the rugged SEL Computing Platform, the SEL Port Server is engineered and tested to withstand harsh utility and industrial environments. It meets utility standards for electromagnetic interference (EMI)/ESD, electrical fast transient (EFT)/burst, surge, magnetic fields, vibration, and shock, and has an operating temperature of –40° to +85°C (–40° to +185°F).

SEL Port Server Details

The SEL Port Server is a rugged, high-density serial-to-Ethernet device that provides secure Ethernet access to serial-connected devices in utility and industrial systems.

Intelligent Serial Port Switch

The SEL Port Server supports communications with multiple serial-connected devices, including relays. It supports an extensive library of serial communications protocols, including SEL protocol. The SEL Port Server supports up to 48 serial ports and expands up to 96 ports when paired with SEL-2905 Serial Port Expander devices.

High-Density Serial Communications

Expand the SEL Port Server serial capacity up to 96 ports by pairing with SEL-2905 Serial Port Expanders. Communications between the SEL Port Server and the SEL-2905 use a dedicated nonroutable link, eliminating IP configuration and simplifying asset management.

Time-Synchronization Source

Provide time synchronization for connected devices that accept a demodulated IRIG-B signal. The SEL Port Server regenerates IRIG-B from an external source, such as an SEL-2488 Satellite-Synchronized Network Clock. If an external time source is not available, the SEL Port Server generates IRIG-B by using its internal clock.

acSELerator RTAC SEL-5033 Software Port Server Extension

The Port Server extension is an intuitive, easy-to-use application for configuring the SEL Real-Time Automation Controller (RTAC) family of products. The extension includes access to acSELerator RTAC tools and its extensible IEC 61131 logic engine for custom programming. Learn more and download on the acSELerator RTAC page.
