SEL-2515

Remote I/O Module

Suitable for use in utility substations or industrial control and automation systems, the SEL-2515 Remote I/O Module provides an easy way to expand inputs and outputs for SEL communications processors. They are far more reliable than remote terminal unit (RTU)-based systems and offer more functionality. You'll receive protection settings management, power report management, high-speed local logic, and direct engineering access.

Control and Monitoring—Extend contact I/O for SEL information processors. Monitor the status of external contacts transmitted via SEL Fast Meter messages to a communications processor, and control contact outputs using SEL Fast Operate commands.

Improved Safety—Circumvent dangerous ground potential rise, and increase safety with less dc ground exposure. The SEL-2515 also adds self-testing and automatic communications path checking.

Status Annunciation—View the state of each of the eight digital inputs and eight digital outputs with LED indication.

Reliable in Harsh Environments—Place near primary substation equipment to eliminate long runs of copper wiring in the substation yard. Fiber-optic cables not only save money on copper wiring, but also improve data reliability.

Details

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.
