SEL-2515 Remote I/O Module
Adds I/O capability (8 DI, 8 DO) using Fast Message.
- Additional Monitoring and Control
Eight digital inputs monitor the status of external contacts that are transmitted via SEL Fast Meter messages to a communications processor. Control eight contact outputs using SEL Fast Operate commands. - Improved Safety
Use fiber-optic cable instead of control wiring to outside apparatus to eliminate exposure to ground-potential rise and other dangerous voltages that can be present in a substation yard. - Easy Application
LEDs indicate the position of each contact output and the status of each sensed input. An "ENABLE" LED indicates that the unit is properly functioning. A "LAMP TEST" pushbutton illuminates all of the LEDs. DIP switches are used to set basic operating parameters. - Dependability
Fiber-optic links reduce or eliminate data errors from electromagnetic interference. The SEL communications processor monitors the fiber-optic connection to the SEL-2515. The communications processor creates alarms when the fiber-optic cabling is damaged, disturbed, or disconnected. - High Reliability and Rugged Design
Built to the same high standards as SEL protective relays, the SEL-2515 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. The printed circuit boards are conformal coated to provide an additional barrier to airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.
- Inexpensively extend contact I/O for SEL communications processors.
- Reduce wiring and improve safety. Locate each SEL-2515 close to a status panel, breaker, or other device with contact outputs to monitor and with inputs to control. Use a fiber-optic link to an SEL communications processor.
- Use in a system with SEL communications processors, relays, and other devices to provide RTU functions, remote event report collection, engineering access, local logic and more, for lower cost and with much higher reliability.
