Trusted Controller Chassis Product Overview

The Trusted® Controller Chassis can be either swing frame or fixed frame mounted and houses the Trusted Triple Modular Redundant (TMR) Processor and Trusted Input/Output (I/O) 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. The Inter-Module Bus (IMB) backplane is part of the Trusted Controller Chassis and provides electrical interconnection and other services for the modules.

• 2 mm x 90 mm (3.6 inches) Trusted TMR Processor slots. • 8 mm x 30 mm (1.2 inches) single width Trusted I/O and / or Interface Module slots. • No user-serviceable parts inside. • Fast assembly. • Minimum tooling/parts. • 32, 48, 64 and 96-way DIN 41612 I/O port connector capability. • Cable entry options. • Convection cooling of modules through the chassis

The Controller Chassis may be populated in different ways dependent on the requirements of each system, to accommodate a maximum of 8 single-width (30 mm) Trusted I/O and / or Interface Module slots and up to two triple-width (90 mm) 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. Modules are inserted by sliding them carefully into their slot position, ensuring that the ‘U’- channels of the module top and bottom casings engage the raised guides of the upper and lower chassis plates. Ejector levers on the modules secure the handleless modules within the Chassis. A 90 mm space must be provided between chassis on a frame to assist the cooling process.
