SEL-2516 Rack-Mount 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. - Safety
Replace control wiring to outside cabinets with fiber-optic cable to eliminate paths for dangerous voltages. All I/O terminals are behind the panel. - User-Configurable Labels
Allow clear indication of system function and status. - Easy Installation and Service
Install rack-mount, compact two rack-unit chassis. Screw-Terminal Connectorized®(STC) blocks for easy replacement of unit. 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-2516. The communications processor creates alarms when the fiber-optic cabling is damaged, disturbed, or disconnected.
- Inexpensively extend contact I/O for SEL communications processors.
- Reduce wiring and improve safety. Locate each SEL-2516 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.
