TMR Digital Input Modules
- Channels: Each TMR digital input (DI) module has three isolated input channels that independently process all data input to the module.
- Data Processing: A microprocessor on each channel scans each input point, compiles data, and transmits it to the main processors upon demand.
- Data Integrity: Input data is voted at the main processors just prior to processing to ensure the highest integrity.
- Signal Paths: All critical signal paths are 100 percent triplicated for guaranteed safety and maximum availability.
- Signal Conditioning: Each channel conditions signals independently and provides optical isolation between the field and the Tricon.
- Diagnostics: All TMR digital input modules sustain complete, ongoing diagnostics for each channel. Failure of any diagnostic on any channel activates the module Fault indicator, which in turn activates the chassis alarm signal.
- Fault Indication: The module Fault indicator points to a channel fault, not a module failure. The module is guaranteed to operate properly in the presence of a single fault and may continue to operate properly with certain kinds of multiple faults.
- Self-Testing: Models 3502E, 3503E, and 3505E can self-test to detect stuck-ON conditions where the circuitry cannot tell whether a point has gone to the OFF state. This is important in safety systems set up with a de-energize-to-trip capability.
- Testing Mechanism: To test for stuck-ON inputs, a switch within the input circuitry is closed to allow a zero input (OFF) to be read by the optical isolation circuitry. The last data reading is frozen in the I/O communication processor while the test is running.
- Hot-Spare Capability: All TMR digital input modules support hot-spare capability.
- External Termination Panel (ETP): Requires a separate external termination panel with a cable interface to the Tricon backplane.
- Installation: Each module is mechanically keyed to prevent improper installation in a configured chassis.
