I/O Cards A variety of analog and discrete I/O interfaces are available tomeet your specific requirements. The following cards supportsimplex or redundant installation: • AI 4-20 mA HART, eight channels • AO 4-20 mA HART, eight channels • DI Dry Contact, eight channels • DO 24V DC High Side, 8channels • AI (Plus) 4-20 mA HART, 16channels • AO (Plus) 4-20 mA HART, 16channels • DI (Plus) 24V DC, Dry Contact, 32channels • DO (Plus) 24V DC, High-Side, 32channels

The following I/O cards are supported in simplex format tomeet your field wiring needs. • AI Isolated, four channels • RTD, eight channels • Thermocouple, eight channels • Millivolt, eight channels • DI 24V DC Isolated, eight channels • Pulse Count Input, four channels (Isolated DI) • Sequence of Event, 16 channels (DI 24V DC) • DI 120V AC Low Side Detection, eight channels • DI 120V AC Isolated, eight channels • DO 24V DC Isolated, eight channels • DO 120/230V AC High Side, eight channels • DO 120/230 Isolated, eight channels

All I/O cards are enclosed in a common form factor that plugsinto the I/O interface carrier. The housing is clearly labeled withthe enclosed I/O card type. All cards have power and internalerror indicators. Eight-channel cards have clearly visible channelstatus LEDs. All cards meet ISA G3 corrosion specifications by the carefulselection of superior electronic components and the use ofconformal coating. Pulse Counters are available on most DI cards. The supportedmaximum frequency varies from 0.1 Hz on AC signals to 75 or120 Hz on 24V DC inputs, and up to 50 KHz on the High-speedPulse input card. DeltaV DCS provides control module level time stamping for logevents and alarms. For greater event resolution the 16-channelSequence of Event DI card can provide signal driven events to aresolution of +/- 0.25 ms per card, or within 1 ms per controller.Please refer to the Sequence of Events PDS for more informationon Sequence-of-event data collection and system options forthis feature. I/O Card Redundancy Redundant I/O cards are available for critical applications. The same card can be used in simplex or redundantapplications.  When installed on a two-wide redundant terminalblock, the cards are recognized as a redundant pair by thecontroller.  The controller scans each card and determines whichcard is acting as the active interface.  When a fault is detected,the system automatically switches to the standby I/O card. DeltaV control modules reference simplex and redundantI/O channels identically and there is no special configurationrequired to take advantage of redundancy Switchover of a redundant I/O card is completed withintwo scans of the I/O bus.  Make-before-break contacts ensuredigital field instruments remain powered and the processis undisturbed.  Analog output signals are briefly driven byboth cards for <5 ms during switchover of the card. Hardware alerts automatically report hardware integrity errorsfor both the primary and secondary cards.  Any event thatcauses a switchover is also reported automatically through thesystem hardware alerts and is logged in the Event Chronicle.
