ICS Trusted TMR Analog Output Module – 40 Channel T8480
Description:
The TMR 4-20 mA Analog 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).
