SEL-2595
Teleprotection Terminal
Securely transfer contacts through a 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.

Rapid Fault Clearing
Take advantage of existing substation communications paths with IEEE C37.94 compliant channels, and send permissive, blocking, and direct transfer trip signals between substations. The SEL-2595 provides better than 5.5 ms back-to-back operating time via 64 kbps IEEE C37.94 communications.
Safety and Noise Immunity
Use fiber-optic cables between protection and telecommunications devices to avoid ground paths and induced noise interference.
Reduced Costs
Employ eight bidirectional channels per terminal to pass critical protection data for pilot protection schemes, such as POTT, DCB, DCUB, and DTT (direct transfer trip).
Reliability
Increase the reliability of auxiliary relay functions with the self-testing capability of the SEL-2595. Digital error detection provides better security than audio tone equipment.
