- Use
compliant IEEE C37.94 Standard Fiber-Optic Interface
Complies with IEEE C37.94
Standard for optical connection to communications
multiplexers.
- Apply
Easily
All settings are made with control switches. LEDs indicate
the state of inputs, outputs, and the channel.
- Operate
at High Speed
Uses one 64-kb time-slot in a digital mulitplexer with
communications time of 8 ms, including 0.5 ms of multiplexer
throughput delay.
- Improve
Security
Digital error detection provides better security than
audio tone equipment.
- Improve
Safety and Isolation
Fiber-optic connections provide isolation from dangerous
ground potential rise, prevent induced electrical noise,
and eliminate signal ground loops. Optoisolated inputs
and contact outputs provide isolation for the field connections.

- Use
existing station communications paths with IEEE C37.94-compliant
inputs to send permissive, blocking, and direct transfer
trips between stations.
- Use
the SEL-2594 to send transfer trips to and from electromechanical
relays.
- Provide
station alarm contacts to a central location for data
acquisition, monitoring, or security systems.
