Triconex TMR Digital Input Module

TMR Digital Input Modules

Each TMR Digital Input (DI) Module has three independent input channels

that independently process all data entered into the module.

A microprocessor on each channel scans each input point, compiles the data,

and transmits it to the main processor as required.

The input data is then voted on the main processor before being processed to ensure the highest integrity.

All critical signal paths are 100% triple processed to ensure safety and maximum availability.

Guaranteed safety and maximum availability.

Each channel regulates signals independently and provides optical isolation between the field and the Tricon.

All TMR digital input modules provide complete and continuous diagnostics for each channel.

Any diagnostic failure on any channel activates the Module Failure Indicator,

which in turn activates the chassis alarm signal.

The Module Failure Indicator points to a channel failure, not a module failure.

Modules are guaranteed to operate normally in the event of a single failure and to continue

to operate normally in the event of multiple failures of certain types.
