ACTUAL APPLICATIONS
Application context for 4201N
Manufacturer documentation places the Nuclear Remote Extender Module in practical safety applications. The three cases below describe different operating tasks in which 4201N performs its documented product-family role with the configured companion equipment.
- 01 · POWER GENERATION
Verify fuel-gas isolation with Nuclear Remote
As part of the gas-pressure signals and double-block valves, 4201N operates in its approved product-family role as a Nuclear Remote Extender 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. - 02 · CHEMICAL & PETROCHEMICAL
Synchronize furnace interlocking with Nuclear Remote
Inside the draft, flame and fuel-train devices, 4201N operates in its approved product-family role as a Nuclear Remote Extender Module. During startup and flame proving, the system uses this function to sequence purge, ignition and fuel permissives, helping it avoid admitting fuel under unsafe conditions. - 03 · OIL & GAS
Observe pipeline isolation with Nuclear Remote
For the coordinated operation of the line-pressure inputs and sectionalizing valves, 4201N provides its specified system function as a Nuclear Remote Extender 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.
