1. Description

The Trusted

TMR 35-120Vdc Digital Input module is a member of the Trusted

range of

nput/Output (I/O) modules. All Trusted

/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 the Trusted

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 Trusted

I/O modules comprise four sections: Host Interface Unit (HIU), the Field Interface Unit

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