Rack-Mount Remote I/O Module
Suitable for use in utility substations or industrial control and automation systems, the SEL-2516 Rack-Mount Remote I/O Module adds additional monitoring for SEL communications processors, featuring eight external contact inputs and outputs (I/O). Status-sensing inputs, clearly marked with an LED, allow clear identification of I/O points. Gain additional functions and higher reliability over a remote terminal unit (RTU).
