Serial Fiber-Optic Remote I/O

Expand the I/O of SEL relays that are Mirrored Bits^® communications compatible without modification to the control panel face. Make I/O status from any relay available to SEL Mirrored Bits communications schemes. Use fiber-optic cable between protection and telecommunications devices to avoid ground paths and induced noise interference.
