ACTUAL APPLICATIONS
Application context for DI 3301
Manufacturer documentation places the Tmr Digital Input Module in practical safety applications. The three cases below describe different operating tasks in which DI 3301 performs its documented product-family role with the configured companion equipment.
- 01 · POWER GENERATION
Observe turbine trip logic during abnormal speed
Across the speed and process trip inputs, DI 3301 operates in its approved product-family role as a Tmr Digital Input Module. During abnormal speed, the system uses this function to vote the configured trip channels and issue the shutdown command, helping it bring the turbine toward a controlled safe state. - 02 · CHEMICAL & PETROCHEMICAL
Maintain storage overfill prevention during high-high level demand
At the control layer of the independent level inputs and isolation elements, DI 3301 operates in its approved product-family role as a Tmr Digital Input Module. During high-high level demand, the system uses this function to stop transfer and close the independent inlet path, helping it prevent the vessel from exceeding its safe fill limit. - 03 · OIL & GAS
Observe pipeline isolation during confirmed line event
For the coordinated operation of the line-pressure inputs and sectionalizing valves, DI 3301 provides its specified system function as a Tmr Digital Input Module. During confirmed line event, the system uses this function to isolate the affected transfer section, helping it contain the event within the intended section.
