SEL-9220

SEL-9220

Fiber-Optic Adapter for SEL-300 Series Relays

Convert the EIA-485 port of an SEL-300 series relay to a point-to-point fiber-optic port. Improve safety, signal integrity, and reliability by using two optical fibers instead of wire to transfer bidirectional serial data plus an IRIG-B time synchronization signal. Apply for instrumentation, protection, automation, and other applications that benefit from economical fiber-optic links up to 5 kilometers long.

Fiber-Optic Link to Remote Devices

Combine the SEL-9220 with a duplex SEL-C808 Fiber-Optic Cable and an SEL-2812MT Fiber-Optic Transceiver to create a fiber-optic link for data and time synchronization to the following devices:
  • SEL-2600 RTD Module
  • SEL-2664 Field Ground Module
  • SEL-2505 Remote I/O Module
  • SEL-2523 Annunciator Panel
  • SCADA System

EIA-485 to Fiber-Optic Interface

Apply the SEL-9220 Fiber-Optic Adapter to an SEL-300 series relay to convert the EIA-485 port to a fiber-optic interface that is equivalent to an SEL-2812MR Fiber-Optic Transceiver. The SEL-9220 uses 850 nm wavelength optics.

Safety and Security

Install fiber-optic connections to isolate communications from ground potential rise and electrical interference.

Accomplish More With a Third Serial Link
For applications that do not use an EIA-485 network, convert the eight-position EIA-485 port of an SEL-300 series relay to a fiber-optic port that is the equivalent of an SEL-2812MR Fiber-Optic Transceiver. For example, connect an SEL-300G Generator Relay to an SEL-2600 RTD Module, an SEL-2664 Field Ground Module, and an SEL-3530 Real-Time Automation Controller (RTAC). Or, add I/O to an SEL distance or feeder relay via an SEL-2505 Remote I/O Module. Easily Apply
Connects directly to the Port 1 connector with positive retention screws. Full-duplex serial data and IRIG-B time synchronization are provided via the connector. Attach with duplex SEL-C808 Fiber-Optic Cable to an SEL-2812MT Fiber-Optic Transceiver at the other end of the link. Increase Safety and Signal Integrity
Isolate devices from ground potential rise and electrical interference through the communications connections using an eye-safe, Class 1 laser product per EN 60825-1.
