- Low-Cost Fiber-Optic
Communication
Send serial data 500 meters using multi-mode optical fiber with standard
V-pin connectors. Use data rates from 0-40,000 bits per second.
- Easy Application
Plug transceiver/modem directly onto a standard 9-pin serial connector (DB-9).
No special mounting is required. Receives power from the host device
via the connector; no separate power supply or power wiring is needed.
Transmits visible light (650 nm) for easy inspection. Requires no jumpers
or settings.
- Secure and
Reliable Data Transfer
Far less susceptible to EMI/RFI than copper links.
- Improved Safety
Provides improved isolation from ground potential rise and other electrical
hazards compared to copper connections.

- Local Relay-to-Relay
Protection Data Links
Connect SEL-2800 Fiber-Optic Transceivers/Modems to the serial port of a
relay and an SEL-2100 Logic Processor. Use SEL
MIRRORED BITS® communications
for high-speed exchange of protection information. Coordinate protection
between generating plants and associated switchyards or between multiple
control houses in the same station. Transfer to backup protection based on
loss of potential or failures detected by diagnostics. Keep the dc circuits
segregated between cabinets. Provide directional element-based bus protection.
- Communicate
With SEL-2505 Remote I/O Modules
Connect the SEL-2800 to an EIA-232 port of an SEL relay or an SEL-2100 Logic
Processor. Install two fibers to the V-pin connectors on an SEL-2505
Remote I/O Module. The SEL-2505 provides eight contact outputs and eight
contact inputs, and communicates using SEL MIRRORED BITS communications-based
logic in SEL relays or the SEL-2100 Logic Processor.
- Receive Data
from SEL-2600 RTD Module
Install an SEL-2800 on a serial port of an SEL-2030 Communications Processor.
Connect a single fiber between the SEL-2800 receive (R) fiber input and the SEL-2600 to
obtain temperature data from up to 12 RTDs.
