Modular monitoring and protection system with local protection loop

摘要

A monitoring and protection system includes monitoring modules that are positioned proximate to locations of interest in a machine system where dynamic operating conditions are monitored. The monitoring modules may be configured to communicate with other modules via an open industrial data exchange protocol. The monitors are also configured to control the operative state of a component such as a relay circuit, either integrated into the monitoring module or provided in a separate relay module. Extremely rapid and versatile response is attained through implementation of a local control loop for control of the state of the relay circuit, which may be complemented by a remote loop that includes a remote monitoring or control system for response to different inputs or conditions.
