ACTUAL APPLICATIONS
Application context for 3401
Manufacturer documentation places the Tmr Digital Output Module in practical safety applications. The three cases below describe different operating tasks in which 3401 performs its documented product-family role with the configured companion equipment.
- 01 · CHEMICAL & PETROCHEMICAL
Sequence toxic-feed isolation with Tmr Digital
Within the feed measurements and emergency valves, 3401 performs its assigned control role as a Tmr Digital Output Module. During loss of containment indication, the system uses this function to isolate the hazardous feed through the defined outputs, helping it limit further hazardous inventory. - 02 · OIL & GAS
Stabilize pipeline isolation with Tmr Digital
At the control layer of the line-pressure inputs and sectionalizing valves, 3401 handles its designated signal or control duty as a Tmr Digital Output 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. - 03 · POWER GENERATION
Synchronize fuel-gas isolation with Tmr Digital
Inside the gas-pressure signals and double-block valves, 3401 serves its documented function as a Tmr Digital Output Module. During confirmed fuel-system trip, the system uses this function to close the documented isolation path, helping it stop fuel flow to the protected equipment.
