1. Description

The TMR 24V dc Analogue Input 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 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 High Integrity 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).
