Which is an example of a control module?
A control module is a collection of sensors, actuators and basic control logic that acts as either a regulating device, a state-oriented device or a combination that is operated as a single device. Examples of control modules are PID controllers and block valve controllers (refer Figure 4.8 ).
How are firewalls used in electrical substations?
Firewalls can be used to separate-high value transformers at an electrical substation in the event of a mineral oil tank rupture and ignition. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment.
What is the subsea control module ( SCM )?
Subsea control module (SCM) is the interface between the control system and the tree. It is the main component of the tree-mounted control system. The SCM contains electronics, instrumentation, and hydraulics for safe and efficient operation of subsea tree valves, chokes, and downhole valves.
Which is an example of a firewall construction?
Firewall residential construction, separating the building into two separate residential units, and fire areas. Firewall, as seen on the inside of a newly constructed townhouse unit, showing how the firewall extends above the roofline. Example of a firewall used to inhibit the spread of a fire at an electrical substation.

How are firewalls used to prevent the spread of fire?
A firewall is a fire-resistant barrier used to prevent the spread of fire for a prescribed period of time. Firewalls are built between or through buildings, structures, electrical substation transformers, or within an aircraft or vehicle.
