- What is an Interlock? | Different Types of Interlocks - AutomationForum
What is an electrical equipment interlock and why interlock is required? The electrical interlocking is done to make sure that the equipment is safe, the electrical interlock is mostly used for substations and they are also used in many industries for the safety of industrial purposes The isolators and switch gears are the protective devices that would provide proper and smooth operation of

I want to understand the difference between process interlock and safety interlock as i came to know that process interlock is configured in dcs, while the safety interlock at Plant shuddown system what is the core difference?
- what is an interlock? | Automation Control Engineering Forum
An interlock is a condition or series of conditions that must be met to allow an operation or process to continue Examples are numerous, but some general examples include: shield interlock- the machine cannot run unless all the safety shields are closed flow interlock - the operation cannot continue unless the coolant flow is adequate pressure interlock - the operation cannot start unless
- Cause and Effect Drawing in process instrumentation
Causes can include a change in the state of a digital input, a High High Low Low alarm from an analogue input, and interlock logic, among other things Effects can include tripping a motor or pump, closing a valve, opening a pressure relief valve, activating an emergency alarm, Beacon Hooter, and so on Detailed Explanation of Cause Effect Drawings Some projects categorize Cause and Effect

- What exactly is permissive | Automation Control Engineering Forum
An interlock can also be a permissive, but a permissive is only a permissive For instance, if I need the level in the tank to be above a certain point to start a pump, it is a permissive, if I also need that level to be above that same point to keep it running, now it has become an interlock
