Description:
Each 64-point digital input (DI) module has three isolated channels which independently process all data input to the module. A microprocessor on each channel scans each input point, compiles data and transmits it to the main processors on demand. Then input data is voted at the main processors just prior to processing to ensure the highest integrity.
All digital input modules sustain complete, ongoing diagnostics for each channel. A failure on any channel activates the Fault indicator which in turn activates the chassis alarm. A TMR module is guaranteed to operate properly in the presence of a single fault and may operate properly with certain kinds of multiple faults.
All digital input modules support hotspare modules and require a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Each module is mechanically keyed to prevent improper installation in a chassis.
The model 3504E High Density Digital Input Module continuously verifies the ability of the Tricon to detect transitions to the opposite state. On this TMR module, all critical signal paths are 100 percent triplicated for guaranteed safety and maximum availability. Each channel conditions signals independently between the field and the Tricon.
