Abstract
The present invention provides for a multispur fieldbus isolator arrangement having a trunk (23) and in which each of a number of spur outlets (210) is connected to the trunk (23) by coupler isolators (24), where each coupler isolator (24) includes a removably mounted modular unit arranged for plug-in connection to the trunk (23) by means of a flameproof connection (29), and where a redundant coupler isolator can likewise be included for activation responsive to failure of a coupler isolator.
Claims20
An electrical circuit comprising:
- a trunk that provides power;
- a plurality of first spur outlets that provides the power to a plurality of first electrical devices;
- at least one first flameproof connector electrically coupled to the trunk;
- a plurality of first spur connectors electrically coupled to the plurality of first spur outlets;
- and
- a first coupler isolator removably coupled to the at least one first flameproof connector and the plurality of first spur connectors,
- wherein the first coupler isolator is removable from the at least one first flameproof connector when the power is provided by the trunk without causing a first source of ignition.
