TrustedTM PD-T8100 TrustedTM Controller Chassis Introduction The TrustedTM Controller Chassis can be either swing-frame or fixed frame mounted and houses the TrustedTM TMR Processor and TrustedTM IO and / or Interface Modules. The Chassis may be panel (rear) mounted by the addition of a Panel Mounting Kit T8380 which comprises a pair of brackets with rear facing ears.

TrustedTM TMR Controller Chassis T8100 Revision and Updating Policy All new and revised information pertinent to this document shall be issued by ICS Triplex Technology Ltd. and shall be incorporated into this document in accordance with the enclosed instructions. The change is to be recorded on the Amendment Record of this document.
TrustedTM TMR Controller Chassis T8100 1. Description Figure 1 Trusted TM Controller Chassis and Backplane The Controller Chassis may be populated in different ways dependent on the requirements of each system, to accommodate a maximum of 8 single-width (30mm) TrustedTM IO and / or Interface Module TM slots and up to two triple-width (90mm) Trusted TMR Processors. The Chassis assembly has screw positions, four on each flange, that are used to enable secure attachment to the side brackets on the frame.
TrustedTM TMR Controller Chassis T8100 2. Inter-Module Bus Backplane The Chassis houses the Inter-Module Bus backplane which is a single, printed circuit board assembly. The Inter-Module Bus backplane provides the electrical interconnections between modules in a TM Trusted Controller Chassis. These interconnections are part of the physical layer communications between modules. Figure 2 shows a simplified top-level block diagram of the Inter-Module Bus backplane.
TrustedTM TMR Controller Chassis T8100 3. Bus Terminations The backplane contains termination circuits for certain bus signals. The terminators are used to reduce signal reflections on critical signals and also to provide default logic levels for open or tri-stated signals. Termination circuits are located at the end slot positions, 1 and 10. 4. Bus Connections All bus connections are triplicated except for the +24V dc external power supply, which is dual redundant.
TrustedTM TMR Controller Chassis T8100 5. Slot positions TM The two left-most module positions are triple width and are used to accommodate Trusted TMR Processors. The first slot is designated Logical 0 in the system configuration and there is no need to configure the second slot. The remaining module positions are designated Logical 1 to 8 from left to right. The modules occupying these slots are defined by the user via the System Configuration Manager – see PD-8082B.
TrustedTM TMR Controller Chassis T8100 6. External Power The backplane has two terminal blocks, one for each of the redundant external +24Vdc power supplies, which are connected to the input power connectors. Redundant power is supplied to all modules in the Chassis. Figure 4 Backplane Back View The dual 24V dc input power supply leads are connected to terminal blocks TB1 and TB2 on the rear of the chassis backplane.
TrustedTM TMR Controller Chassis T8100 7. Smart Slot Referencing For a Smart Slot configuration, the secondary slot is not required to be unique to each primary slot. Instead, a single secondary slot can be shared among many primary slots. This technique provides the highest density of modules to be fitted in a given physical space.
TrustedTM TMR Controller Chassis T8100 8. I/O Connectors Up to eight DIN 41612 I/O connectors, slotted into the chassis back-plate, can be provided for connection to TrustedTM IO and / or Interface Modules to their sub-systems. Double and single connector options are available where applicable. Figure 7 Connector to Chassis Attachment Features Each I/O connector has an earth tail which should be fixed to the cable saddle bracket across the rear of the chassis using M5 x 10 Pan Head Taptite screws.
TrustedTM TMR Controller Chassis T8100 10. Chassis Installation The TrustedTM Controller Chassis is installed into a swing-frame or fixed frame as shown in Figure 9 using M5 x 12 Pan Head Taptite screws. Figure 9 Installation of Chassis Note that only the inner pair of holes in the mounting ears are used at this stage to secure the Chassis in the swing-frame.
