The Ampcontrol IPM integrated protection relay (Version IPM V2.0) is an intelligent protection relay based on microprocessor technology. All of the tripping logic and outlet control is performed by the microprocessor, so that virtually no external control is required.
The IPM integrated relay provides the necessary functions required for protecting electrical outlets supplying underground mining machinery, powered by reeling or trailing cables, in the metalliferous industry. The relay can also be used to provide optimum overload protection of motors used on conveyors, pumps, fans and compressors. All of the protection functions are combined into a compact, plug-in unit, which can be easily changed out to minimise down time in the event of a problem with the relay.
The IPM integrated protection relay can provide machine data transfer through the use of a Remote Termination Module (RTM) connected between the pilot and earth at the machine end of the trailing cable. Through the use of the RTM, the relay parameters are automatically up-loaded from a remote machine when a cable is inserted into a power outlet. The IPM’s remote start capability can also be accessed by use of Ampcontrol’s Remote Termination Module.
The IPM integrated protection relay provides all the necessary protection functions to control the various types of mining machinery. The default status screen allows unskilled personnel to determine what is required to apply power to the machine. The Ampcontrol IPM integrated protection relay provides protection functions for:
