SEL-2595 Teleprotection Terminal
Securely transfer contacts through high-speed IEEE C37.94 optical fiber interface. Use the SEL-2595 Teleprotection Terminal to send and receive up to eight relay contacts directly over a pair of optical fibers or through a digital T1 or SONET multiplexer.
- Use Compliant IEEE C37.94 Standard Fiber-Optic Interface
Complies with IEEE C37.94 Standard for optical connection to communications multiplexers. - Operate at High Speed
Provides faster than 5.5 ms back-to-back operate time while occupying a single 64-kb time-slot in a digital multiplexer. - Improve Security
Digital error detection provides better security than audio tone equipment. - Improve Safety
Replace control wiring to outside cabinets with fiber-optic cable to eliminate paths for dangerous voltages. - Annunciate With User-Configurable Labels
Allow clear indication of system function and status.
- Use existing station communications paths with IEEE C37.94-compliant inputs to send permissive, blocking, and direct transfer trips between stations.
- Use the SEL-2595 to send transfer trips to and from electromechanical relays.
- Provide station alarm contacts to a central location for data acquisition, monitoring, or security systems.
The SEL-2595 communicates through a remote multiplexer using IEEE C37.94 protocol, eliminating all electrical connections in the communications path.
