ed links for data and power. The data link is synchronized and monitored for variance. Both FIU and HIU have on-board temperature sensors to characterize temperature-related problems. The power supplies for both the HIU and FIU boards are redundant, fully instrumented and testable. Together these assemblies form a Power Integrity Sub-system. 1.8. Sequence of Events Characteristics The Module automatically measures the field voltage and current to determine the state of each output channel. An event occurs when the output transitions from one state to another. When a channel changes state, the on-board timer value is recorded. When the TMR Processor next reads data from the Output Module, the channel state and real-time clock value are retrieved. The TMR Processor uses this data to log the state change into the system Sequence of Events (SOE) log. The user may configure each output to be included in the system SOE log. Full details of SOE are contained in Trusted Sequence of Events and Process Historian Package, publication ICSTT-RM243 (PD-T8013). 1. Description Trusted TMR 24Vdc Digital Output Module – 40 Channel 8 Issue 14 Rockwell Automation Publication ICSTT-RM280N-EN-P 1.9. Output Switch Structure The Digital Output Module provides a TMR switch topology where the load is driven by a total of three fully monitored, fail safe (6 element) switch channels, one physically resident on each FIU in the Module. Any single switch or entire slice failure is designed to leave two of the three fail safe switch channels operational to power the load. Figure 3 Output Switch Structure The upper switches as shown in Figure 3 are denoted as N.O. (Normally Open), and are controlled by the FIU on which they are physically resident.1 The lower switches are depicted as N.C. (Normally Closed), and are controlled by the “upstream” neighbouring FIU.2 Note: In this context, N.O. is defined as being in the off state in the absence of control signal power, and similarly, N.C. is the on state in the absence of control signal power. These switches are constructed from enhancement mode MOSFETs and are both guaranteed to be off in the absence of Module power to create gate voltage signals to bias them on3 (unlike electromechanical relays for example). The reason that the lower switches are specified to be on in the absence of control signal power is to allow two channels to power the load should an entire slice fail. Even if an entire slice fails, the surviving output circuits will carry the neces
