ROC - Earth Continuity Relay

Product image The ROC Earth Continuity Relay has been designed to monitor the pilot earth continuity resistance of a trailing or reeling cable connection to a mobile machine on a fault-limited system.

Overview

Certifications

  • AUS 02.2551X MDA [Exia] 17029

Description

The relay has been approved intrinsically safe and is suitable for use in a Zone 0 hazardous area.  The relay picks up if loop resistance is less than 39 ohms and drops out if the resistance exceeds 45 ohms.  Shunt resistance between the pilot and earth phase conductors has to be greater than 500 ohms.  A time delay on pickup and drop out is also provided.

The relay is powered from a 110VAC power supply.

The relay is suitable for remote operation and when ‘remote’ has been selected, a remote stop/start station is used to operate the relay.
