DeltaV Product Data SheetJanuary 2013 – Page 8M-series Intrinsically Safe I/OIntrinsically Safe Power SupplyThe intrinsically safe power supply accepts 24 VDC power and converts it to 12 VDC to power the DeltaV I.S. I/O cards. Thenumber of I/O cards that can be powered by a single Intrinsically Safe Power Supply depends on the I. S. I/O card type.Optional power supply redundancy is supported by adding power supplies at a rate of n + 1. The following table gives thespecifications for the DeltaV I.S. I/O Power Supply.I.S.

DeltaV Product Data SheetJanuary 2013 – Page 9M-series Intrinsically Safe I/OLocalBus Isolator• The DeltaV LocalBus Isolator protects the I.S. I/O from fault voltages from AC main power supplies. The LocalBus Isolatoralso links intrinsically safe I/O with non-intrinsically-safe I/O. The following table gives the specifications for the DeltaVLocalBus Isolator.LocalBus Isolator SpecificationsDimensions Centimeters InchesHeight 11.0 4.3Width 4.2 1.7Depth 16.0 6.2Weight 250 grams 8.7 ozCarriersAll DeltaV I.S. I/O cards are contained in modular 8-wide carriers. Connect the carriers in the most efficient configuration foryour plant. The carriers have multi-pin connectors to ensure that I.S. I/O is never connected to non-I.S. I/O.Power supplies for I.S. I/O modules using field wiring have their own modular carriers. These carriers connect between the I/Ocarriers.Use a LocalBus isolator to connect I.S. I/O with non-I.S. field wiring. The LocalBus isolator resides on its own carrier.
