2 Isolation is provided be-tween the field and RTP chassis ground. The RTDs are notisolated from one another; they share a common power supplyfor the precision excitation current sources. A guard band aboveand below the full-scale signal range allows signals exceedingthe specified input signal range to be detected by conversion is performed by a 16-bit switchedcapacitor successive approximation A/D converter. No field ad-justments are necessary after initial factory trim. The A/D con-verter calibration is continually checked by monitoring aninternal fixed voltage, which is passed through every activecomponent on the to noise is further enhanced with a single-pole, lowpass input Bus self-test functions are performed for all input data, sta-tus and command transfers to and from the RTD card .

3 Eachtransfer is performed twice (all the data bits in the second trans-fer are inverted.) Both transfers are then compared to insurethat no errors exist in the data path between the RTD card andthe processor. I/O Bus slot address and control signal conten-tion tests are also performed. Cable detection tests verify thatthe termination cable is properly connected to the card . Anyerrors are reported in the card s status and triple redundant configurations can be implementedby adding one or two additional 3007/04-000 RTD cards. Twoor three cards may be connected to the RTDs in parallel usingthe 3099/34-000 RTD Triple Termination Module. When usingredundant configurations, the signal validation ( input voting)function can be used to validate the inputs received by thenode processor.

4 Redundant configurations increase is the Best Technology for Your Investment,Here s Why:The 3000 is a multi-processor architecture that deliversexceptional Performance and ComprehensiveDiagnostics. The results speak for themselves: AReaction Time of 12 msec, true 1 msec SOE (Analogand Digital), an MTBF of greater than 3000 years, anMTTFS of greater than 4000 years, and a PFDavg of5x10-5. Compare these numbers to any other Proof Test Diagnostics means it will never benecessary to shut down at the proof test online downloads of logic and configurationchanges do not require a periodic shut down like othersystems. Compare this functionality to any Suite Software: One-time price includes unlimiteduse of Logic Development, Alarm Manager, DataArchive and Historian, and HMI without hardware orsoftware keys.

5 Compare this functionality and priceto all other , a Safety Instrumented System (SIS) shouldalways take the process it protects to a safe state whenit is required to do so, and it should never interfere withthe operation of the process at any time. The 3000does this better than any other 3007/04-000 RTD card s hot swappable design hasbackplane interface logic to protect the card from damage,and to prevent control and data signal degradation on thebus, when plugged into a live RTP chassis.
