SEL-2100 High-Speed Logic Processor
Interconnect up to 15 devices using resident MIRRORED BITS^® communications

Connect up to 15 SEL-2505 Remote I/O Modules to one SEL-2100 Logic Processor. Each module provides eight digital inputs and eight digital outputs.

SEL-2505 Remote I/O Module

Replace long runs of bulky control cables with a compact fiber-optic cable. Isolate and eliminate hazardous ground loops and induced voltages.

The SEL-2126 Fiber-Optic Transfer Switch is a high-speed communications device that senses digital inputs to route data streams between 6 optical port pairs to either of two other transfer ports.

SEL-2594 Contact Transfer Module
Securely transfer contacts through high-speed IEEE C37.94 optical fiber interface.

Use the SEL-2594 Contact Transfer Module to send and receive up to eight relay contacts directly over a pair of optical fibers or through a digital T1 or SONET multiplexer.
