1. Description
The TMR 24/48V dc Digital 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).

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).
