1. Description
The TMR 24V dc Analogue Input 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 Trusted
TM 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 comprise four sections: Host Interface Unit (HIU), the Field Interface Unit
(FIU), the Field Termination Unit (FTU) and the Front Panel Unit (or FPU).
