1. Description

The TMR Zone Interface module is a member of the Trusted

range of Input/Output (I/O) modules.

All Trusted

I/O modules share common functionality and form. At the most general level, all I/O

modules interface to the Inter-Module Bus (IMB) which provides power and allows communication with

he 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).

Figure 1 Module Architecture

All High Integrity I/O modules are made up of 4 sections: Host Interface Unit (HIU), the Field Interface

Unit (FIU), the Field Termination Unit (FTU), and the Front Panel Unit (or FPU).
