The integrated relay provides the necessary functions required for protecting electrical outlets supplying underground mining machinery, with compliance to AS/NZS 2081.2011 and is certified for use on outlets supplying loads in hazardous areas.
All of the protection functions are combined into a compact, plug-in unit, which can be easily changed out to minimise down time. The IPE System consists of the IPE Relay, IPE Base, Remote Termination Unit (RTX), an interface platform (PIP), three 1000:1 Current Transformers, and an Earth Leakage Toroid.
The IPE Relay has three output relays, 2x MCR contacts for the main contactor control and 1x CBR relay used for circuit breaker control.
The IPE relay incorporates Ampcontrol’s latest machine recognition technology through the proven Remote Termination Unit (RTX). The RTX pilot communications has improved noise tolerance, resulting in a more robust installation.
The IPE Integrated Protection Relay is approved for use in mining operations. For the protection of mining equipment in hazardous areas the relay is to be installed within a flameproof enclosure. Control and interfacing with the relay is performed through a locally mounted PIP, visual interface can be through a panel mounted screen (PIPS) or installed within a flameproof enclosure where needed. Alternatively, interfacing with the PIP can be achieved remotely over Ethernet communications.
Ampcontrol’s Protection Interface Platform (PIP) is a is an intelligent controller that is used to interface with the next generation of Ampcontrol Integrated Protection Relays. The system standardises the interface between the latest protection relays offered by Ampcontrol and any external interfaces (PLC or Networks) where required.
