Page 7: Product Overview
• Front Panel Module status LEDs indicate Module health and operational mode (Active, Standby, Educated). • TϋV Certified IEC 61508 SIL 3. • Outputs are powered in isolated groups of eight. Each such group is a Power Group (PG). Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... -
Page 9: Description
Inter-Module Bus (IMB) which provides power and allows communication with the TMR Processor. In addition, all Modules have a field interface that is used to connect to Module-specific signals in the field. All Modules are Triple Modular Redundant (TMR). Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... - Page 10 Figure 1: Module Architecture All High Integrity I/O Modules are made up of four sections: Host Interface Unit (HIU), the Field Interface Unit (FIU), the Field Termination Unit (FTU), and the Front Panel Unit (or FPU). Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021...

Page 11: Field Interface Unit (Fiu)
DC Digital Output Module, the FIU contains one stage of the output switch structure, and sigma-delta (ΣΔ) output circuit for each of the 40 field outputs. Two additional ΣΔ circuits provide optional monitoring of the external field I/O supply voltage. Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... -
Page 12: Host Interface Unit (Hiu)
LED indicators for the Front Panel. For every type of Trusted I/O Module, the FPU contains the Slice Healthy, Active/Standby, the Educated LED indicators, and the Module removal switches. Additional bicolor LEDs provide status indication for the individual I/O signals. Serial data interfaces Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... -
Page 13: Line Monitoring And Output States
Data input from the IMB is stored in redundant error-correcting RAM on each slice portion of the HIU. Received data is voted on by each slice. All data transmissions include a confirmation response from the receiver. Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... -

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 Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... - Page 15 Switch 1 and Switch 2 are in the off state. Their “home” FIU. The home FIU, supplies an independent control signal for the “downstream” FIU FSS. For an unfaulted transistor. Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021...

Page 16: Switch Diagnostics
To support safe operation, the Output Module is equipped with a series of switches that provide source power to a group of eight output channels, a Power Group. The output Module Group Fail-Safe Switch (GFSS) is intended Rockwell Automation Publication ICSTT-RM451D-EN-P - March 2021... - Page 17 GFSS can still be de-energized by stopping the comms clock. If a slice fails, the watchdog on the HIU times out and resets the slice, this shuts down the FIU power supply and the associated GFSS control signal also de-energizes.
