TRICONEX TRICON 3700A Analog Input Module Differential DC Coupled 0-5VDC
16-Point Supervised and32-Point Supervised/NonSupervised Digital OutputModulesDesigned for the most critical controlprograms, Supervised Digital Output(SDO) modules meet the needs ofsystems whose outputs remain in asingle state for extended periods of time(in some applications, for years). AnSDO module receives output signalsfrom the Main Processors on each ofthree channels. Each set of three signalsis then voted upon by a fully faulttolerant quadruplicated output switchwhose elements are power transistors, so that one voted output signal is passedto the field termination.Each SDO module has voltage andcurrent loopback circuitry coupled withsophisticated online diagnostics thatverify the operation of each outputswitch, the field circuit and the presence of a load. This design providescomplete fault coverage without theneed to influence the output signal.The modules are called “supervised”because fault coverage is extended toinclude potential field problems. Inother words, the field circuit is supervised by the SDO module so that thefollowing field faults can be detected:• Loss of power or blown fuse• Open or missing load• A field short resulting in the loadbeing energized in error• A shorted load in the de-energizedstateFailure to detect field voltage on anyoutput point energizes the power alarmindicator. Failure to detect the presenceof a load energizes the load alarm indicator.All SDO modules support hot-sparemodules and require a separate externaltermination panel (ETP) with a cableinterface to the Tricon backplane.
