Abstract: A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.

Abstract: A relay interface module that is commutatively connectable to at least one I/O device and a controller, wherein the relay interface module is configured to provide data from the I/O device to at least one controller in a distributed control system (DCS) via a communication interface. An application related to a particular I/O device may then be executed freely on any controller present in a DCS without losing real time connection with the associated I/O device. Data can be transferred from an I/O device to an associated application executed on a controller such that the real time connection between the I/O device and the application being executed is maintained.
