3636R | Triconex Relay Module

Each 64-point Digital Input (DI)module has three isolated channelswhich independently process all datainput to the module. A microprocessoron each channel scans each input point,compiles data and transmits it to theMain Processors on demand. Theninput data is voted at the Main Processors just prior to processing to ensurethe highest integrity.All Digital Input Modules sustaincomplete, ongoing diagnostics for eachchannel. A failure on any channel activates the Fault indicator which in turnactivates the chassis alarm. A TMRmodule is guaranteed to operate properly in the presence of a single fault and may operate properly with certain kindsof multiple faults.All Digital Input Modules support hotspare modules and require a separateexternal termination panel (ETP) with acable interface to the Tricon backplane.Each module is mechanically keyed toprevent improper installation in achassis.The Model 3504E High-DensityDigital Input Module continuouslyverifies the ability of the Tricon todetect transitions to the opposite state.On this TMR module, all critical signalpaths are 100 percent triplicated forguaranteed safety and maximum availability. Each channel conditions signalsindependently between the field and theTricon
