DC/DC power supply 9180

multiple-outputmodularfor fieldbus

The 9180 range should be selected for all new applications. Its unique N+1 redundancy approach provides flexibility to the system designer meeting the initial demands of the project with 2 power supply modules/segment, whilst having the ability to add a third power supply later to meet expansion requirements. The advantage to the operator is typically a 25% saving in initial capital cost compared to a conventional, 1+1 redundant architecture. High system availability is achieved with the use of passive components for power conditioning, galvanic isolation and power regulation delivering redundant fieldbus power at up to 28V, 500mA/segment. The product range also includes power supply modules that can be used to provide power for segments with Ex ic spurs, to be used in conjunction with MTL F300 range of Megablock device couplers and F30 Ex ic adaptor. 9180 range redundant fieldbus power supplies offer the following benefits: • Flexible N+1 redundancy • Can reduce initial capital cost by 25% whilst supporting future expansion • Low power dissipation • Choice of rising cage clamp screw or spring clamp terminals • Screen passthrough or ground option without accessories • On-line diagnostics option • Pluggable trunk surge protection option • Support for Ex ic spurs when used with F300 range of Megablocks and F30 Ex ic adaptor
