Description

The TMR 24 Vdc Digital Output 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 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).

All High Integrity I/O Modules are made up of four sections: Host Interface

Unit (HIU), the Field Interface Unit (FIU), the Field Termination Unit (FTU),

and the Front Panel Unit (or FPU).
