Remote I/O Modules

SEL-2505 Remote I/O Module

• Extends contact I/O economically on SEL relays that are MIRRORED BITS^TM Communications compatible.
• Adds MIRRORED BITS to any protective relay (digital or electromechanical) or other intelligent electronic devices with contact output.
• Monitors channel activity and integrity with 22 status LEDs; alarm status for visual feedback of system performance.
• Increase reliability and reduce project costs by using two fibers instead of 32 large-diameter wires, with less material expense, reduced trench and raceway requirements, and less labor for design, documentation, installation, testing, and maintaining.
• Withstands demanding industrial operating temperatures of -40°C to +85°C (-40°F to +185°F).
