1. Description

The TMR 4-20 mA Analogue Output module is a member of the Trusted

TM

range of Input/Output (I/O)

modules. All Trusted

TM

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 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).
