Schweitzer Engineering Laboratories
Remote I/O Module
The SEL-2505 Remote I/O Module has eight digital inputs, eight digital outputs, and a fiber-optic communications port. Use two optical fibers instead of 32 wires between outdoor or remote equipment and the control building to reduce costs, improve safety, and boost reliability. Or, connect an SEL-2505 to a fiber-optic port or transceiver on a protective relay to add digital I/O. Wire the SEL-2505 I/O to relay I/O to add SEL Mirrored Bits teleprotection.
